Pleased to note that you people are actively curating this tag. But if you are really serious about it then why do you guys allow #actifit tag for your platform? You can easily exclude such non-relevant tags from your platform using holger's simple script for this purpose?
If you don't care about this, I take it as you are not serious about curating content for your own platform. I won't mind you blacklisting me as currently, I'm not invested in your platform anyway!
