It makes it impossible to filter domains because the actual spam domain is "protected" behind a shortened URL.
Edit: I'm talking about the #books tinyurl spam: https://hubski.com/domain/tinyurl.com but as you can see there there are some legit posts that used a shortened URL too.
The spammer keeps making new accounts, so filtering users is not effective against this and I don't want to filter the #books tag.
Sorry all, we are at insom's wedding. :)
We will bring the hammer down after this joyous occasion.
