What the hell is happening here?

Tweet

I've just posted a question about how come my posts number was reduced from 318 to 312 just now and now the same strange thing occrred to me once again. I posts at least 7 to 8 discussions and responses this evening but now my total number is 316. I don't care about the earning, I just don't understand what the hell is happening? What did I say have violated the rules here?
