In 2017 I was running my bitcoin blog; one of the first blogs created in the space, when someone contacted me from an official BitcoinTalk.org. They asked for 5 BTCs to post a banner ad on BT. Seeing that the email was coming from an official BT address, I sent them 5 BTCs.
Two weeks later after not hearing from anyone, I received a message from BitcoinTalk.org saying their email was hacked and the ad offer was from a scammer.
5 Bitcoins today = $40,000 USD. I really miss it. I wish BitcoinTalk.org would at least say sorry.
