Who (what) is MindlessElectrion exactly?
Only the best spam buster out there. The information on it's profile basically says everything. It reports/removes/nukes (newbie) accounts if they post malware/spam/etc.
I'm thinking of something like the following:
Instead of randomly intruding into random people's threads, a topic starter could "opt in" to enhanced spam scrubbing by placing a special bbcode inside the OP, that (among other things) contains a "percentage spaminess threshold" that applies to all replies.
Then, I have J.A.R.V.I.S monitor the thread and score each person's reply, and the ones that fall short of the spamming score, I report these replies, or maybe I relay the posts to your bot if you can offer a faster way to delete those posts.
As an example (taken from a random thread, and
not intended to criticize anyone's posting behavior), let's pretend the Bitcasino ANN thread wants everyone posting to stay strictly on-topic about gambling or its casino, and opted in to spam scrubbing and signals to delete any reply with even 10% spaminess score. Then when posts like the following are made:

All of these replies would be trashed. Though considering these are legendary members, I don't know if your bot analyzes them as well.
I am almost 100% sure that Bitcointalk itself will not enforce any enhanced spam requirements, so perhaps a minimum spamminess score for any given thread could be set to 90%, in which case, all (recent, within the past 2 weeks) posts that fail to be even a little substantial are reported/deleted en-masse.
