Well, someone mentioned it elsewhere in regards to Facebook, saying that the site would be less likely to IP ban members that break the rules in case they accidentally ban a family member/someone in the same company or school. And it got me thinking: Is this an actual trend? Do larger sites avoid using IP bans more, in order to prevent users sharing the IP being accidentally banned with the offending user? Or are they just as willing as traditional forums to use them for persistent rulebreakers? What do you think?
