" I never died to him I observed him as a good/neutral/evil"

And this is the type of thing that makes me ill. People who have
multiple characters they are developing can not help but use info
they have gained from one character with the next. They also carry their prejudices from one character to the next so all interactions are tainted.

Seriously this is a rather large issue for me because it means that
one can scout you with an ally then turn around and log on their
opposing character to hunt you down for X, Y, or Z reasons.

Not only do you get to know what the targets are wearing but what
they prefer as tactics, what they are looking to do, where they may
be etc etc. This is the path of least resistance for which the Imms
have no ability to monitor. And while I have absolutely zero proof that this occurs sometimes there are just too many coincidences for me to feel comfortable playing CF.

Of course this view is strongly influenced by my rational that playing more than one character at a time(no not multi-charring as in logging them in at the same time) diminishes the effort you put in any of them hence me playing a single character.
