Information About URL/Website Ban

I would like to find out if my website has been banned by facebook and, if so, if there is a penalty time length. I have looked around the forum and I have seen people say its permanent, but I was wondering if they have tried waiting a month and if that makes a difference.

I think sending too many messages with this url in it eventually led to the account getting roadblocked. Tied new account, sent one message with url and account instantly got logged out and roadblocked. Only sent about 100 messages with url between two accounts in about an hour and then the third account is the one that got logged out instantly (no warnings for the other accounts sending message with url). No messages saying url is spammy, no warnings. Am trying to figure out what exactly is happening here. The url definitely seems to be the key factor here, but no warnings or messages of spam/abuse, just account automatically logged out and roadblocked (asking for phone verification again). If anyone has had any experience with this stuff, I'd like to know more.

Also, I wanted to know if anyone had any advice on how to check to see if facebook has definitely banned my url and if there is anything that I can do. It is real business website and I am trying to find out more about this. Any info would be appreciated. Thanks.

once url is banned then its banned and thats it. scrap it and get a new domain. and to check if domain is banned is easy. try posting it in a status update or comment. if it posts then its not banned. if its banned you will get a error message
