A while back a plumber looking for shower door specs blithely took a relative's browser here. It's more likely aimed to get traffic from "basco.com" (single 's'), Briggs and Stratton, or looking again, maybe this aviation corp. bassco.
Anyway, symptoms were: claiming the ISP had blocked our IP address (No), locking up the immediate browser window (chrome), generally complaining and fishing for information. That's all. Hoped this was the right place!
