Start using Google Ads and scammers will use it to advertise phishing websites pretending to be Ledger and Trezor. Search "Ledger" on Google and sometimes you will get a scam website asking for your seed. We don't need Newbies coming here, saying that they got scammed by an ad they saw on the forum (also, ponzis).
Google sucks. At least theymos knows what he is doing when he accepts someone's banner in the ad rounds.
Another thing is that Google only allows certified licensed gambling websites to advertise their businesses. So lack of competition and more repetition of ads.
