How do blue dragons react

To reckless use of magic, especially now? I know that it was basically their purpose to regulate magic, but how did they usually go about preventing this?

Also a bonus question: does this include the use of all magic? Like would a blue dragon care about the use of fel, light, and void? Or is their concern only arcane
Since the aspects lost their power I think it's safe to say that the scope of the Dragonflight's duties have been significantly reduced. Not only that, but the blue flight specifically has very few members left. The duties of regulating magic really took a back seat during most of recent history since the War of the Ancients, when Malygos went out of commission. Magic therefore, was not really "regulated" in the way that the Timelines, or the Emerald Dream was by those flights. Even when Malygos was around and functioning, one has to wonder where he was during the evolution of mortal spellcasters. The Highborne really began abusing magic right under his nose, and the whole war could potentially have been prevented if they intervened first.

"Regulating the use of magic" seems to have taken a few different meanings depending on who is operating at the time. During the Nexus War, Malygos the original blue aspect took this to an extreme after he finally came to and declared that anybody using arcane magic without blue supervision is essentially a renegade. They recruited all the mortal spellcasters they could compel to join in with their mage hunters, militarized much of the whole flight, and started using specialized tech to divert all ley lines on the planet to their focal point in the Nexus, essentially depriving all mages on the planet from a big source of arcane power. Many displays of greater magic require being situated on a ley line, or at an intersection of many, in order to channel the required amount of magic as opposed to just willing it out of ones' self.

Since the blues came under new management and the aspects lost much of their power, this has taken a different, less hands-on meaning, being "the age of mortals" after all. Kalecgos, the new aspect, has a seat on the Dalaran Council of Six, so he gets a vote in matters involving what is probably the greatest/largest society of mortal magic users on the planet. In that way, he helps oversee things. The blues also help safeguard many magic artifacts that would otherwise cause untold damage in the wrong hands. As seen in Legion, they sometimes need help keeping these things safe, as there was really only one adult dragon left in the Nexus to protect these items. Dalaran also helps protect other similar items, and with the aspect on the council you can infer that the Blues are at least aware of what is where.

Whether this includes all magic, it is harder to say. Definitely mainly Arcane, and surely not Light. The distinction being that Arcane magic stems from the planet itself - from ley lines, which can be damaged if abused. Therefore there is a solid reason for why and how this magic must be regulated beyond just supervising mortals and hoarding magical objects. Fel magic, on the other hand, is pulled directly from the Twisting Nether - it does not have roots in the planet. It would be much harder to prevent a spell caster from accessing fel magic than arcane (which also requires a lot more "technical" knowledge, so to speak). Same with void, as it isn't a force that stems from our plane of existence. Should the Blues have cause for concern if a bunch of warlocks began corrupting the planet with fel-magic - definitely! There just wouldn't practically be as much they could do.
Historically, the Blue Dragonflight regulated arcane magic (and only arcane). The reason they didn't interfere with the War of the Ancients is because Deathwing used the power of the Demon Soul to wipe out most of the flight.

Currently, the Blue Dragonflight has been officially disbanded by Kalecgos, so there is little to no regulation being done by them.

Ever since Malygos went off the reservation and Kalec got depowerd, no one really cares what the Blues think anymore. They still haven't recovered form when Deathwing all but decimated the Flight back in the War of Ancients.
“Oh oh! I can answer this.” Kersia pulls out her spectacles and pushed them up her nose. “SO! Reckless use of magic might lead to interesting results. Do I care that you recklessly use magic? Well, like six or so years ago I might of, even a few years ago it might have irked me some… But now I am happily content to watch you blow yourself up. Better you than me, am I right?” She snickered. “After all, how best to gather data than some field research observing some fool entwine their mana in just the wrong way and cause their feet to become tiny or their left hand giant! Ahaha! How utterly inconvenient for you, but then I learn what not to do.”

“Now, what really gets me curious is the users of other magic schools. After all, I don’t really know those schools that well. None of my test subj-friends use fel magic, so that is really interesting to me. If you use it recklessly, what could happen? I dunno? Do you know? If you do, you should write a thesis on it so I could learn too. Sharing is caring. Don’t be so stingy with your knowledge.”

Kersia paused. “Xinaria is kind of stuck up now. Not like… mean… but she wont let me run any more tests on the uses of light magic. She did let me help her with her lightforging trial. Learned a lot with that but I wouldn’t say it is reckless. I did hear recklessly forcing light magic on people might lead to you blowing up though. Interesting and requires further study. Vyn won’t answer my summons for blood draws and testing, which is unfortunate. Stupid druid. I mean… not stupid. Answer my letters, I want to see what more you’ve learned for fire druidism… please?”

She thought for a moment. “You know, I don’t know any void users yet either. I should befriend one of those void elves and run some testings… What happens when you recklessly use the void? Do you get trapped in the nether? Oh! Maybe you hear things. I bet they know all sorts of interesting things, I should see if Umbric has published a book or thesis on it.”
