They aren’t. I opened the first 2 threads, and I know what they are about. If people are giong to fill it with nonsensical flooding then it’s not my fault of the dynamics of the thread change, but the idea of those two threads if greatly different. Same goes for the third thread you mentioned.
Ok sure, right away 
Please read the joke again. If someone was to say that to you, i bet your first reaction would be to slap that guy and to feel embarassed. I have a sense of humor, and believe me i’ll be the first one to laugh at a dirty joke. But that does not mean I’m going to keep that dirty joke in the G rated forum. If someone wishes to share that joke then do it through pm.
And if you think a joke is vulgar, then it’s your responsibility as a user to use the “Report a Post” option, and bring our attention to that post. Haath par haath dharnay say aur phir kehnay say keh moderators are biased aur kuch nahin kartay, us say kuch nahin honay wala. Na sirf tum log frustrate ho gay, balkay hum log bhi hon gay.
And FYI, i did receive a notification that that particular joke in question was offensive.
this is coming from someone who begged to be made moderator and was removed for breaking every single moderator rule. World’s a funny place
