Re: "Incidents" or "reports of incidents"?
My spam filter logs that many misuse attempts in a year. But I haven't reported them to plod.
On the other hand, I have (in my capacity as an open source developer) occasionally been in receipt of misdirected complaints. The kind of scenario where luser installs Apache web server, sees Apache default page or error page, and sends a very angry and incoherent complaint to Apache about having hacked them. I daresay Plod gets more of that sort of nonsense than we do.
