1. High quantity of threads
2. High quantity of doxxing
3. They're about an underage girl
4. They don't really fit with the rest of /wsg/'s content
5. Lots of discussion instead of content (especially recently) on a content-oriented board (/wsg/)
6. Seth and Maddie might've contacted the moderators recently
Honestly, It's no surprise the moderators hate /bbg/. Hell, They hate all 4chan users.
I doubt they'll actually give their reasoning, but if they will, they'll probably respond on the IRC. /qa/'s more of a shitposting board than anything.

IMO thus far, it seems as if they mostly just care about confining all TikTok shit to one thread. If that's the case, the most likely ending is that /ttg/ and /bbg/ will have to merge, assuming that the mods don't back down and, honestly, that hurts me and the few /ttg/ guys more than the /bbg/ fags.
