If you're being an asshat or using one without everyone's consent, you can be suspended if someone decides to report you. Unofficially, you only want to be parsing a group of friends, FC, or static where everyone agrees to it. If you parse a random PF or DF group with people you don't know who haven't consented to being parsed, you will probably end up getting hit with the ban-hammer.
