How do you detect URL shorteners? Simply by checking for a redirect using curl, or do you check against a list of urls? Domain review would be a lot of work to implement, i hope we can avoid that.
I currently just use a list of known URL shorteners domain names, and it reduced the spam a bit on the subreddit I moderate.
Problem is that someone needs to maintain that list.
Every list needs a maintainer ;)
EDIT: Here's a preliminary list

And that maintainer needs to be trusted. But if we manage without a list, there is no need for extra trust nor maintenance work.
Fair point.
