I just had a thought, what if that site is a mole trap? We sign up there they capture our IPs and then cross check those with posters at DUmmyland?
Nah none of them goons are smart enough to pull something like that off.
That's always a concern of mine, but I notice my ISP (internet service provider) changes my number once in a while, and they tend to be widely-different numbers. Sometimes the first numbers are just two digits, other times three digits. A couple of times, it's been just one digit.
This isn't something that happens daily or weekly or monthly on a regular basis; sometimes for months and months I'll have the same number and then boom! it'll abruptly change for a few weeks, and then change again for another random period of time.
I dunno why that is, but I'm not an expert on computers and the internet.
I still have a lot left to learn in life, and learning computers and the internet is, like, 30,682nd on the list. I'm concentrating on learning more-useful information, such as "how to get along with other people, "how to be a better person," " how to be more effective in kicking primitive ass," and somesuch more-useful things.
