This is a good addon, really a must have imo.
The only thing i miss in it is a whisper by lvl restriction filter,
like the retail addon badboy have where i can set it to 60,
and the only ones who can send me whispers are lvl 60s,
with exceptions being people in you're own guild and friend list.
There was an addon for this back in the day called Jspam,
have not ben lucky to find one that works with 1.12 version,
so i will fix it when i got the time. But would also be cool to only
have to have one single addon for all chat spam related issues.
Might use this one as inspiration or something of that nature.
