Hi, I'm nephele a developer of Haiku.
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 had a screenshot of the second "nice" renderer diff here aswell, but am not allowed to post it as a new user )
Discuss this on our forum.
