Well, I'm pretty sure that the ones reading this thread, who had any of their alts tagged by Lauda, must have started searching the databases of their forum accounts to find those accounts and bring them back to live since now their negative tags are removed.
Good point! I'll compile a list of accounts tagged by Lauda, and sort them on their "Last Active" date. I don't think anyone is going to just copy 2000 red tags, so this should make it more manageable.
They're fast!
ChrisLandin reactivated today. He stopped posting the moment Lauda tagged him (in June 2017), and made only one more post in December 2017. Now he's back.
