I died to her several times, was never looted, and RP'd with her just fine.

Basically the playerbase does it to themselves. You annoy a character with 100% assassinate by bitching at them OOC about full sacs so they do it to you too. I don't really full sac unless it is done to me first, but I'm never 'nice to' or 'RP with' people that have gone OOC on me either. I just don't talk to them. So it becomes a self fulfilling kind of thing. The player base in general says XYZ about you on forums so it becomes common logic, then people start treating you that way IC, then you become what they hated about you.

As long as you treat people with respect in general, they will afford you the same respect. Tiiga was no exception to this.
