I have enjoyed many hours of listening to recordings of scambaiters calling telephone scammers and harassing them. Their goal is typically explained that, by wasting the scammers' time, they prevent the scammers from harassing someone else.
Scammers, usually either based in India or staffed in other countries by Indian expatriates, have posed as Microsoft Tech Support, the Internal Revenue Service, Canada Revenue, the Social Security Administration, etc and have stolen millions of dollars from people since these scams were first created. Recent arrests in India and the United States of scamming operations appear to have done little to stop scams from continuing. It's easy to start a scam operation, once you know how it's done, especially if people who participated in one scam operation simply move on to start their own.
While wasting scammers' time with baiting is enjoyable to do and to watch others do, I think that it would be far more effective to identify the phone numbers used by scammers, discover the company under which their phone number is registered and then contact that company in order to have the number shutdown.
Twitter is my primary source for the initial discovery of phone numbers being used by scammers, but I will keep my eyes open for other sources,
My primary tool for discovering the company that owns the number is Phone Validator, which is usually reliable. Otherwise, you can use Free Carrier Lookup. If these two sources disagree, simply file reports with both of them. However, neither of them can trace toll-free numbers.
For toll-free numbers, I use either 800ForAll, TollFreeNumbers.com or Toll-Free Number Search by ATL Communications.
In case none of those sources can provide me with the information I need, I have to do a little extra digging and make my best guess.
The following is the contact information for all companies whose numbers have been used by scammers. If the information is out-of-date, I would appreciate corrections posted in the Comments section of this post and I will update the information here.
In order to keep the list up-to-date, I will remove numbers after about two weeks unless reports continue to be posted about them. Do not scambait the numbers listed on this blog. If you received a call from one of the numbers listed here, simply use the provided contact information to file a report. When making your report, please remember to include the date and time when you received the call.
