I usually pop onto twitter every day just to see if there's any new news from the sims team and I, for sure see the nasty replies to every single tweet from The Sims twitter account, the Guru's twitters accounts, to players that have positive things to say about a pack or feature or just TS4 in general. It's extremely toxic.
On Twitter it only takes one person to say something negative, then 100's of sheep (followers) chime in with a similar or same rant. Sad thing is, I've read many times people said they say they don't like TS4 even tho they secretly do because they get bashed if they praise any part of it. Twitter is a very clique-y, popularity site, the more likes and followers you get from posts you make, they more important it makes you feel. That's the generation The Sims is marketing to, that demographics. Young people who only want to follow the "cool" kids and not speak on their own behalf.
