This edit suggestion was approved by a user with 44K reputation. If he had clicked the link, he would have realised that the link actually led to a pornographic site.
The suggested edit was done by a user who has since been banned for posting the same link in an answer of his own, on the same question.
This obviously shows that this user was not paying attention to the suggested edit and just clicked "Approve".
So yea, can we all just be aware that stuff like this happens, and we really should look closely at suggested edits. I understand that an average user probably can't tell whether a link was actually improved, if they have no experience in that topic, so then they should at least skip the review. But as this link was blatantly pornography, this shouldn't be a hard one.
