I had originally planned to retire, but in honor of MGE iT's departure I've come back for one final parting gift to you all. Below is a link to a spreadsheet of alts, it's formatted somewhat poorly due to the fact that it's initially categorized by ip addresses (which have been redacted) and to add to that there are going to be false positives of people who live with one another (and people who played at lans). Because it is a spreadsheet, though, it retains search functionality despite this. Have fun embarrassing your friends.
Goodbye.
