I'm not active on Linkedin but you can see changes as they are made in the github repo I linked. Or you can subscribe on the ascii-collab site to see what people are drawing.

In regards to dealing with spam, by far the most effective trick is to get very little traffic (how foolish of me to post my site here!)
The site also saves old changes even if they have been covered up so it's possible for me to remove vandalism and restore what was underneath.
Lastly I have a theory that people are more likely to spam if they see that there's lot of spam already and they are less likely if it looks like everything so far was written with intent. So I try to stay on top of removing spam as soon as it appears.
