I found that one technique scammers use is taking popular domains like “microsoft.com” and change one letter hoping that u will misspell it and go o their site. The good news is that you can use this to find their numbers. By purposely misspelling domain names. Like for example “apple.com” you can try to put “spple.com” since the “S” is close to the “A” it is possible people miss-spell it, and they will be taken to a scam site, where u can find the number, and share it at the TSU forums.
they are called typosquatted domains, this is talked abt in the scambait guide - Getting started with scambaiting! - A Guide
Apologies, I may have missed it.
