These are possible reasons why you might not be able to access a web page:
1.You requested a very large number of pages in a very short time, causing problems for servers (this can happen if you hit 'refresh' over and over, for example).
2.You could have been banned by mistake; sometimes automated banning policies are too strict and some IP addresses are banned by accident. If you don't think that you've done anything to warrant a ban, this is most likely the case.
3.You (or someone with the same IP address as you) might be using a script or program to download pages from this site automatically. This is forbidden by some sites terms of service.
4.Someone with your IP address may have violated another section of our terms of service (for example, behaving disrespectfullytoward other members of the site)
5.You might be using a VPN. If you are using a VPN, and other users of the same VPN are abusing the service, then you'll be automatically banned as well. There's not much sites can do about this; you'll have to turn off your VPN in order to continue using the site.
6.Your computer may be infected with malware or spyware that is making automated requests server and causing problems.
