ok, i will try to explain (english is not my primary language),
The idea is to know how twitter could know if your link in tweets are spams.
Same as search engine, it use spider-crawler. this could help twitter to index tweets, in other words, each time you' re posting a tweet, a spider visit it and, if there's a link, it follow your link.
So it s possible to think if twitter spider find and visit a link which is too much repeat, it will consider: this link is a spam! then it will blacklist it , and ban.
This happend when you are posting direct link from some cpa network offers.
Then, what's the deal? A solution could be to redirect twitter spider to another page when it visit your link.
Well, as i said in my previous post, the twitter spider name is : Twitterbot.
There's some some functions that you can insert in your website page to do a redirection. This function could be written in html, in php, in javascript and with an .htaccess file.
Here i tried to give a solution with an .htaccess. Just create a file with this name, .htaccess, and insert this few lines. Just replace redirecturl with your link you want to redirect Twitterbot. Then import this file in your server.
Hope this is better for you now ...
