You can also track that person when he/she changed name.
You're right... but who would bother keeping an ongoing list for years?
but we are unable at all to prevent he can come back with an alt, with same toon with name changed or whatever.... doing the same things than before "umdercover".
Get a shivtr page for your guild. Applications tab - Admin - Audit Log: can see all the IPs of those who applied/commented on the applications.Site admin tab - Audit Logs: can see all the IPs of those who have done something on the forum. I could add more here, but I don't want to give away all my secrets. Having a good memory and an alt guild works too. I remember about 90% of the names of those I've dealt with, and they're hundreds. I also recognize people by the way they misspell (perks of studying linguistics, I guess). And of course, last but not least, check their gears. Their most important item is their flyer; many people get name changes, but forget about changing that.
this is bad for me
