So I decided to check on my server to see how it's handling all the bots and we're up to nearly 10,000 banned IP addresses, plus I caught another one being abusive with thousands of requests in the last 24 hours; #SemrushBot. No idea who #Semrush is, some kind of SEO or marketing outfit looks like, but it seems to have started yesterday. The day before it was just a couple hundred, but yesterday it was several thousand so now they get a 403 and a firewall ban.
