Just a couple things:

1- Some sites are not working (look at armt.info releases).

2- I realised that because of your site being automatic with the past of time you will have thousands of warez forums and blogs which will cause overload to your bot and hordes of repeated posts (and also Spam) so maybe you could limit the amount of sites based on their rating (If a rating system is implemented, something like katz where there is a staff that valuates the sites) so If a site ever get?s a negative rate you will drop it from the bot list for 1 month (for example)
