Are account merges prohibited?

I have previous accounts I've owned here since 2010 which are all now on a self-requested ban.

Is it allowed to merge them into one account? I have so many vouches, However, I have never included them in a sale I have made which didn't concern this particular account. Considering all the vouches on my previous accounts are my vouches It would be perfect if a merge could happen?

Also, my join-date doesn't really help my case when it comes to dealing with business. Since I've been a member here for 5 years and not a year or so.

Just wondering guys. Thanks

You can't transfer vouches, donation status etc.
