We want fans to really behind the things they like. This is a positive site.
Activities that are recognized as attacks are not allowed and may result in account suspension.
Examples would be fan content uploads that mock the creator, hateful posts etc.
It is very possible to be critical of a creator while still being supportive if you see something they don't like. For example they upload content that they do not like, it is ok to say so in a constructive manner. A positive outlet for this genuine concern would be to make a fan poll asking if they like the creator's old style or new style etc.
