yeah, I was testing and had the color in there... it auto removes now along with the [Robin Autovoter posts

See my fork. :P Changed a bunch of things there.

I'm not seeing any difference. But I did change it to use e.target instead of e.currentTarget because long running chat will get laggy

Can you explain what the code inside the if statement is doing? I understand that it's searching for text with "[Robin Autovoter", but what exactly is /[\u0080-\uFFFF]|(?:\ doing

It's removing any unicode (special characters) that people like to post (swastikas, hearts, triangles, faces ...)

Ah I see. So let's say I wanted it to remove everything listed in addition to the phrase "voted for GROW", I'd change the if statement to if (/[\u0080-\uFFFF]|(?:\[Robin Autovoter)|(?:\voted for GROW)/.test($(this).text())) {...} ?

yes... but the current version of the script will remove the redundant "voted for" posts as well.

You should hash the string instead of using it as the key.

Done!

It's getting way too complex for a simple one day script ... but it tracks spamminess of each user now.
