I usually don’t mention anything about being a scambaiter because carriers have a prejudice against scambaiters since the scammer blaster incident. I know we aren’t all the same but carriers have that association and they may take the report as some form of vigilantism versus just a concerned person reporting fraud.
It’s important to realize that the employee reading these emails may not have any legal authority or know how to act with something like this whereas if they are sent emails with numbers that are using their network for malicious activity then they can take action to verify the claim and follow their procedures for handling such reports.
I also don’t mention legal action because it just doesn’t come off well. The best way imho is to be calm, factual and give the representative reading your email something that they can take action on. The rep can terminate numbers for fraud but they may not be able to enforce or even suggest wide sweeping policy changes like better KYC enforcement.
Over April, the DeMurrage group and a few other teams have reported a total of 83 numbers to Magicjack. Out of these, only 10 have lasted long enough to get posted on our carrier reporting thread. Magicjack is a responsible carrier and does take action against abuse on their network. I would not call them complacent, non-responsive or irresponsible.
PS: These are my own opinions and do not represent the opinions of DeMurrage or the scammer.info team.
