Maybe you should PM the campaign manager for this and explain that you're the real owner of this account. Signed message is a must.
If you read the campaign thread you'll find all the rules. You have to read more than just the original post.
If you weren't banned from the campaign (and just removed) you'll have the opportunity to appeal after 60 days. If you contact or request review before 60 days you'll significantly hurt your chances of any consideration to get readmitted.
I don't know if you bought this account or not...and I don't know what Lauda's opinion is on those types of accounts. What I do know is the long period of inactivity is a HUGE RED FLAG of breaking a rule that is meant to keep previously banned members of this forum away from participating in the forum. You should find out how long it takes for your inactivity warning to retire. And if you did buy this account, you shouldn't use it for a signature campaign.
Follow the rules and you'll get to enjoy this privilege.
It is a privilege.
