I think the only way you're going to find out IF you can come back is to actually try to enter the country.
A thai consulate isn't going to know and would sell you a visa whether you're black listed or not, because all they do is sell visas.
It's gonna take tryin' to enter the country to check and see.
OR Google is your friend, there has to be some service out there that can check to see if you're blacklisted (for a fee).
