I think 评论 are fine as long as they're not emotionally, sexually, racially, physically, etc. harmful to those it's aimed at. There's no excuse for being an asshole, but a lot of people don't get that, unfortunately.
Ppl shouldn't be allowed 2 say bad words on Fanpop. There should be officials that go check out 评论 & if someone is swearing, they get rid of the 评论 & suspend the person 4 a 日 from Fanpop. That's what I think, anyways.
