I moderate the Haiku forums aswell, and recently there have been spammers signing up an then posting double links, and hiding those as if it were one link with a hyphen. Seeing as discourse already has the “first post very fast” warning, I thought perhaps there could be a warning/flag for new users that include two links, or include links that do not match their actual URI, while having something that looks like an URI in the link title.
This is a screenshot of me removing the spam link, this has happened three or four times now. (each time with the spammer creating a new account)
I kind of like this idea, though if people want to abuse the system with misleading links or similar stuff, they’ll always achieve this somehow.
I get you’re specifically asking for a feature, but preventing trust level 0 users from posting links could suffice for most cases. Reaching TL1 is fast if you’re a legit user, but spammers never will. So I’m just mentioning the Post links allowed groups setting in case it would help people who come by on this topic.
This is frustrating, but as a TL0 I bellieve you can just post another message with the 2nd picture.
Instead of prohibiting TL0 from posting links, you could also reduce the Newuser max links site setting to 1. This could prevent the 2-link problem while allowing the sharing of one link.
New user limitations can be a little annoying for new members, as you noticed when you wanted to post more images.
This is true, but even those who manage a Discourse forum usually complain instead of spending a few minutes reading.
