These discussions are fine to have - but there are two main camps and very little chance the opposing sides are going to come to a common ground.
AT THIS TIME - and I say that - because things can and do change over time, GDKP runs for GOLD ONLY - are allowed.
That is an entirely different discussion from advertising.
How to get your account reported, and if going against any of the rules, actioned…
-
Annoy your realm mates with frequency.
1a. This can be spam - no matter where it’s put. -
Advertise in the wrong places.
2a. Various channels have a purpose - this matters no matter what the advertisement happens to be. -
Advertise outside sources of communication.
3a. Discord, websites, etc. - this is against policy. -
Advertise on a low level character or cross-realm.
4a. Policy says the character has to be participating in the run or at the very least ABLE to participate in the run (server/level)
Any of those things can get you reported - and actioned if you run afoul of policy.
