On a typical day, I have seen 50 to 100 login attempts from a variety of IP addresses, all of which are blocked very effectively by the Wordfence security plugin. I never use the 'admin' username in WordPress, and I always use very strong passwords.
Most likely, the miscreant has infected a bunch of computers with malware that is generating all of these login attempts, and the owners of these computers have no idea what is going on; or, it may be that he is running through a list of proxies, and thus the attempts appear to originate from differing IP addresses.
The website receiving these attacks is of no importance to me, but it is on a shared hosting account where I do have some important assets. So far, none of my other sites has been attacked in this manner.
My question is: should I just ignore this idiot, or is there anything I could do to annoy or discomfit him in some way?
