Is there a problem for us if people mistakenly report our number as the source of spam calls? The FTC page says
https://www.consumer.ftc.gov/blog/2017/ ... nted-calls
many call blocking tools rely on blacklists. Those are databases of phone numbers that have been reported as the source of illegal calls. In addition to the number, the data the FTC releases will include the date and time a person got the unwanted call, the general subject matter (debt reduction, warranties, home security, etc.), and whether it was a robocall. Companies will be able to use this information to help identify which calls should be blocked or flagged. Even if a scammer fakes caller ID information — so the number you see isn’t the scammer’s real number — reporting it can make a difference.
This sounds like faking our number as a caller-id could amount to a denial of service attack, if our number ends up on blocklists. I wouldn't be surprised if my longtime habit of reporting junk emai to Spamcop has gotten me on some spammer's shitlist.
