Why do people like to come on these sites to troll now ?

I noticed that the last few years Yahoo and Similar Worlds have gone down hill and turned into troll land it seems like nobody answers on either site seriously anymore. Similar Worlds use to be a lot nicer than Yahoo but now I young female usere on there stalking me they're as mean as they are here on Yahoo they think I'm the same person with millions of accounts making up **** but I'm not I had an account on there not long ago but it got deleted because I put every mean female user on blast so I had to make a new account. I think these females are trying to hit on me but I'm taken also I'm a little young for them. It's like Yahoo I'm having to report and block everyone now. These stupid Anonymous trolls always call me Sapina and Sherlock the crying troll and say get help for your MPD and call me an OP. I keep reporting somehow they find away around to still answer my questions. I don't think reporting is helping and you can't block them. Back when Similar Worlds was Experienced Project it was really nice same with Yahoo before Verizon bought it and let all these young teenage trolls in. I dont get why changing a site turns it into troll land and makes users mean. Why does nobody take these sites seriously anymore ? Why is almost everyone so mean now ?
