If you are having problems viewing this site or getting in to your photobucket, it is because they were hacked. Some people are having problems and some not. Here is a quote from a discussion of it:
this sounds the most logical to me!
As it seems like only some people see that "hacked" page and others can access it fine, this doesn't sound like an attack on the photobucket site itself but rather an attack on DNS server where photobucket.com record was changed to point to different IP address, and anyone using those DNS services will be affected by it.
this sounds the most logical to me!
