Yesterday, on Travel.SE, I stumbled in a sequence of edits to reviews that were just "user removed post content and substituted with spam content".
At first I thought the user was defacing his own posts, then I realized he was editing other users posts ('cause he edited one of mines). Then I noticed he/she/it had just one reputation and I thought that maybe he found a way to hack the site, so I asked on Travel Meta and got confirmation that everybody can edit everyone's post, because there is the review queue to filter out spammer.
Now, I'm confused.
On the SE network you need reputations even to be allowed to breathe; there is a entry level for everything apart from spamming the site? Seriously? I need a minimum rep even to add images to my questions, but I can choke the review queue with just a bunch of freshly registered accounts?
I think, I strongly think, that editing someone else's post should be allowed only with a minimum rep, let say 20. There is no way a user that never posted a question, that never posted an answer, then never ever used the site, has any real interest in spending its time editing other peoples posts apart for malicious intents.
