Limited axx or....

[BarBeQue]

I just clicked the top link of the latest hack list on the home page:
[vB 3.0.0] New Postbit - by gamevn
https://vborg.vbsupport.ru/showthrea...threadid=63629

And got a no permission message.

BarBeQue, you do not have permission to access this page. This could be due to one of several reasons:

Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system? 
If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

What caused this? Are there some higher level forums that not everybody has axx too, or could it be a thread / hack that got removed cause it violated some term?
In the latter case, shouldn't i get a "this thread doesn't excist" message, instead of no permission?
