Most people assume: "We are being discriminated against because they are IP checking." (IP checking causes positive/negative differences in the rewards given to players.)

When in reality it is more that player actions are often consistent across characters as most players have tells (I am also guilty of this.) If those player habits happen to be bad habits, such as cussing someone out OOC after a PK loss, it immediately throws up a red flag and tends to color future perceptions of said character badly.

So a more likely causal interpretation might be: "I have a tendency to act in a particularly unappealing way due to my (bad) habits, thus I am being given the cold shoulder as a result."

You could also flip the argument the other way to explain rewarding behavior, which may be even more likely. The people getting constant rewards just happen to have hit on and refined the "how to be rewarded" formula and apply it to all their characters. (Individual player habits cause positive/negative differences in the rewards given to players.)

Anyway, I'd thought I would chime in. Apologies to Torak as this isn't death-thread specific. Not trying to steal your thunder there.
