Newbie links

[fxmulder]

Hello, I run cryptotc.us which allows new coins to post offers for over the counter trading.  I've noticed when newbies post links to my site, part of the link is replaced by a suspicious link stamp.  I was told by a moderator that this is typical for newbies and most links are handled this way, but they are able to post links to several other sites including links to their new coin without this change.  Is there a way to prevent this replacement from happening when newbies post a link to my site?

Thanks
