We are using Mikrotik for a BGP blackhole server that collects BOGONs from CYMRU and we also have our servers (web, email, etc.) use fail2ban to add a bad IP to the Mikrotik. We then use BGP on all our core routers to null route those IPs. The ban-time is for a few days, and totally dynamic, so it isn't a permanent ban. Seems to have cut down on the attempts considerably.

This is not an optimal approach, and most providers are unlikely to engage in such behavior due to its potential negative impact (I'm assuming you mean via S/RTBH and/or flowspec).
