Hello,
On our forum we are once again getting a larger amount of spam and one new trick I noticed that could be avoided by discourse is the following:
People seem to start posting spam posts (or posts without links and then editing them in) and put the hyperlink to the spam page to the dot at the end of a sentence. This is quite invisible and annoying to check every potential spam post for, so it would be amazing if discourse could require a link to be at least X characters long.
Besides spam this would also fix the accessibility issue of having links that are so small that they are really hard to hit.
