Hi guys, I have found a scammer number and site.
Here is an image of what it looks like so you don’t have to go to the awful browser locking site:

the site is: katlidepx.tk/gb/main3/indexx.php?pn=ICs0NC04MDAtMDg2LTkzNzQg
The UK number is +44-800-086-9374
I will try find other country numbers. I think you just have to replace gb in the site to any other country.
When they ask you what you were doing when you got this pop-up, say you were trying to go to netflix and this came up because that is what happened but I mispelled netflix on purpose to get the number. (Don't say that last part) The number is toll-free.
Guide to trolling this number:
Step 1:Call them using firertc or anything except your normal phone number as they will spam call you.
Step 2: Talk to them and when they ask you what you were doing when you got this pop-up say you were trying to access netflix.
Step 3: Pertend not to be too good with computers and fall for them.
Step 4: When they ask you for your name or ANY personal details, use hxxp://www.fakenamegenerator.com/ and use those. I recommend copying the information into a notepad for easier access. When going onto the site, replace hxxp with http or https. Or just go on www.fakenamegenerator.com
Step 5: Before calling, practise a mini script and what you will say to what questions.
Step 6: Set up a virtual machine. I'm sure there are many ways to do that. Look it up on YouTube if you don't know.
Step 7: If you don't want to step up a virtual machine, just waste their time on the phone (firertc or phone number spoofer application etc...)
This guide was for beginners. This is a new account and is my first post on it but I do have experience with scambaiting and I'm just sharing what would have helped me when I first started out a year ago.
