Well, “undeniable proof” is a really low bar for you with your huge over-generalizations. However I use my ignore function in LFG chat as a filter. Sure there are some genuine lowlifes on there, but the majority of my ignores are for people using LFG to advertise services. If Blizzard properly kept people from violating the ToS, I wouldn’t really need it. But since it is not a monetary loss for them, they are not really interested.
Thank you once again for being Activision/Blizzard’s authorized representative and official spokesperson. I do hope your pay doesn’t affect Bobby’s bonus though or they might have to reduce you to keep paying him. 
Thanks.
