it's a sensible rule if you look at the intent. so rather than doing away with it because it doesn't work, they should instead reinforce it... maybe with a more sophisticated filter or more diligent moderators
You have to be Xper Level 2+ (150+ points) to post clickable links or embedded images and videos. This is so that spammers and scammers cannot come in and immediately post links that GAGers will click on, putting their computers and personal information in danger. Because we catch most spammers while they're still Xper Level 1, this prevention helps a lot :-)
The Xper Level restrictions can always be found in our FAQ as well.
