I really don't think theymos would implement something like this. It's too open to abuse.
Yeah, I really wasn't a fan of this, though it was at least some barometer for trolls, but it was also abused or could give the wrong impression. Back in the day people used to use the ignore button if they didn't like what you were saying or just because you were on a signature campaign and they'd be open about telling you that. People shouldn't be lit up like trolls just because someone doesn't like what you're saying. How many of us would be marked as trolls just because there's certain people who don't like you or have a few alts they can do the same on just to try impact you negatively. By all means, use the ignore button if you don't want to see what certain people are saying but that shouldn't effect how others perceive you.
