Excellent post and analysis.... always the best from @paulag !!

In your "Strange Activity" section, is it possible to clearly identify spammers by comparing the text strings of post and counting the number of times each text string is posted. Repeating the same text string of a post (comment) over and over again is a clear sign of spamming the block chain. Just a thought for automatically identifying spam.

Keep up the great work and analysis you do. It is great needed and appreciated.

Have a great weekend!
Steem on,
