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.
