You got the answer to your question -- what else do you want to know?
I need help to investigate Blitzboy and need DT members to tag him
Blitzboy was tagged by yahoo on 1/18. I don't normally issue tags for ban evasion but you can feel free to leave a red trust yourself.
If he's an alt of a banned account then he should be banned, of course, but I'm not 100% sure if mods ban accounts based on sharing a wallet with a banned user. In this case all the addresses in the wallet most likely belong to the same person -- it's not like an exchange or coinjoin wallet. I will send a report and see what happens.
