Can someone explain to me why homosexuals like to spam their shit on unrelated boards when they already have:

>>>/lgbt/
>>>/cm/
>>>/hm/
>>>/d/
>>>/y/
>>>/u/
>>>/soc/
>>>/b/

I really am tired of seeing so many recurrent trap and gay threads on boards like /a/, /v/, /co/, /r9k/ and so on. At least bronies stay inside /mlp/, why isn't moderation forcing homos and bis to stay inside their own boards?
