I recently found my old acc with all my old hats and stuff. But i've been using my new acc which now has my spar stuff. The email for that acc is most likely inaccessible because of how dated the acc is, so is there any way for me to merge the 2 accounts? I've heard from various people that its been done before.  

They don't merge accounts  

I think this feature was only available in like 2009 or 2010 something like that just from what i heard  

Requests for support should be taken to support.toonslab.com. As the others before me have stated, account merges aren't granted. However, if you prove to support that it is your account and the email can no longer be used, they might change it for you.
