Clean-up is definitely needed but this may not be the best approach.

I've personally created designs for clients from crypto projects to local hotels, took the time (usually a couple hours or so) to create, only to be flagged here as "spam" on the sole (only) post titled 'my latest work:'. Why? Because a whale (I won't mention) thought only STEEM content should be allowed.

Everyone's definition is clearly different, the rules of what is spam and what should be cleaned up should be hard-coded not selected by people.
