Thank you all for your patience. I'm keeping a close eye on it these days (all day long, throughout the day)
I just blocked 7 more IP address ranges.
BUT unfortunately, I can't sit at the PC all day. I need to eat, take care of my kids, take care of my household, etc. so during those times, a bot flood could come in.
I have some other ideas, which would take time to do (not a LOT of time, but not 5 minutes either).
I also don't want to go into too many details, in case anyone malicious is listening.
