Unfortunately when you have a popular forum you become a victim of spammers. So are we. In order to make the life of spammers a bit more difficult we've just limited when you can post images and links.
Now you need 2 posts before you can post a link or an image.
We're currently fighting spam, our moderator team is continious online to fight spam, we have plugins that prevent spam posts to be posted and still things come through.
We've lately seen an increase in posts with 1 pixel images which could be used for unknown reasons. We hate to enforce restrictions but hope to fight these spammers this way, we hope for your understanding.
In case the restriction doesn't help and/or gives too much trouble we'll ofcourse revert the decision, as always your feedback is much appreciated!
