#[0] in Snort, is my block list public?

I block all "hell thread" spammers but it's not sustainable as accounts are for free and noobs that fall for "hell thread" spam get blocked accidentally.

Please let me set a threshold to not get notified if **the event mentions more than 20** or better **the author is not a follow of any of my follows**. Both of those could still be tracked but under a different tab "probably spam".
