Even though its probably been stated in this thread before, as a reminder:
ONLY CONDUCT ESCROW TRANSACTIONS ON THE FORUM
A few rules that anyone attempting to trade on the forum should abide by:
1. Ask for a personalized signed message from a PGP key or Bitcoin address previously associated with the user. Make sure the escrow has used the PGP key or address before, and it isn't a new key/address made by the scammer.
2. Don't use Telegram or other off-forum communication platforms for escrow deals! Do every part of the deal on forum, via PM or better yet, its own thread.
3. Ask around about the quality and availability of escrows before settling on one, as the first post in this thread hasn't been updated for over 4 years. That's like 40 years in forum time, meaning everything could have changed between now and then. You can even ask in this thread and someone will probably get back to you (don't trust the word of new or minimally-ranked accounts, of course).
