"URL currently inaccessible." Why does this happen?

1. No, it is not alright. If it's written online, someone owns the copyright, whether আপনি know who that is অথবা not. The ফ্যানপপ Terms of Service (which we all legally agreed to when we became users of this site) explicitly states that we will not post any copyrighted content without the prior written consent of the copyright holder. Just about any user will প্রতিবেদন violations of this, if only to make it less likely that ফ্যানপপ will be sued দ্বারা irate copyright owners.

2. Some লিঙ্ক are inaccessible because ফ্যানপপ is unable to নিশ্চিত the link as valid. This could happen for a variety of reasons, including: the target site is not replying to Fanpop's queries because of slow network traffic (some web hosts have bandwidth limitations, and if too many requests for a প্রদত্ত page come at the same time, the host service will start to reject some), the target site is not responding to ফ্যানপপ for some other reason (poor set-up of the host and/or web server, system incompatibility), the domain is not legally accessible to ফ্যানপপ (certain countries and IP addresses are restricted for companies in the United States), the site page is only accessible through a গুপ্তশব্দ অথবা other secured access (Fanpop doesn't have your passwords for other sites), অথবা the domain has been identified দ্বারা ফ্যানপপ অথবা others as an invalid domain in the past (every web site has a "black list" of sites with which they won't communicate, either because of hacking, spam, অথবা other high-risk activities). There are other possibilities, I'm sure, but I তালিকা the ones that occurred to me right away, roughly in the order of likelihood (as I see it).
