Last night, Shrednow was attacked by comment spammers who left more than 50 pornographic comments on stories throughout the site. I had set up anti-comment spam measures, but they did not fend off this defacement of our site. Therefore, I have decided that from now on, comments will only be accepted from logged-in users. It should be no problem for any legitimate visitor to Shrednow since accounts are so easy to set up, but it will set up one more barrier to those who would spam like this. The same will be true for link submissions – if you have a link of interest to the Shrednow community, you now must be logged in to add it the site.
