The correct answer has already been given - if they are uploading legal, non x10-TOS violating files, you should be fine.
However, I would STRONGLY advise keeping a very close eye on the forums, either via post-moderation or only allowing certain users permission to upload. As soon as any 1 file uploaded breaks someone's copyright, it breaks x10's TOS, and can be permanently suspended.
Edit: Seems I should have looked first and posted second; I'm curious how you missed one of your links contained the word "NULLED" right in it which violated that developers copyright, along with several other scripts that likely broke copyright as well.
In the future, should you ever end up with a new account at x10 again, you are responsible for -everything- on your account, including the stuff other users post. That's why you need to keep a close eye on users. That said, the download in question was uploaded by the Head Admin of the board. That's generally a -bad- thing.
