I don't know if it has to do with also adding an image but for about 10 minutes now, I've had my posts rejected after hitting submit. I seem to be able to post without pictures, though.
If you want a full image to load up instead of a crappy postimg one then use an imgbox link. It isn't "super blazing fast" as claimed but it does a fine job at near full resolution.
There was a little crypto spam problem in the last few days 🙁 It was added to the word filter to prevent the new ones, I guess the settings are not perfect yet ( or it's just a little bit too strict 😀 ) I let the pending threads out to play 🙂
