Photobucket links get changed to obsolete

[tek]

Forum URL: googleearthcommunity.proboards.com
Somehow the domain name "photobucket.com" in Photobucket links is removed when a post or edit of a post is submitted. And this happens only with Photobucket links, among all others the users use.

What I did first was to check it in my test forums. Nothing weird... So it could be some plugin or script failure, OK.

I disabled all the plugins and tried it in a fresh theme with no luck in having those links posted unchanged.
 
Is there any further way to find out the problem?

Look in your censored words (Admin > Security > Censored Words). I see the following entry that would cause the issue you described:
