I dont have complete anonymity, no one does. There are ways of reading forums without being a member. If a legal case were to ensure as a result of something posted here, the hosting company may have to hand over log files and data. Its happened in loads of cases on other forums, all the time.
Perfect example is when footballers end up 'roasting' some girl in a hotel, and the media get hold of it, football forums clamp down on anyone posting about the incident even though its made the papers. Why? because it can be used as evidence against them.
If you think you have complete anonymity then you are very wrong. Dont blame me, i didn't make the rules
