Cleo,
Dependent on what your bot calls itself.. some webmasters will redirect the bot via robots.txt etc.. I get the same probs.... looks like a redirection.. but the site is there..
Sub-domains also ring ALARM BELLS with me... Firstly for scammers, but secondly for webmsaters that move hosts and bloody well forget about the subdomains they had previously set up...
Anything submitted to me that even vaguely "smells" polish gets rejected now..
Will PM you my current polish list and the some other info.
