Probably a scammer

I was researching this dude out here. Managed to find this discord. We had a conversation that led to me trying to initate a transaction with him trough a MM.
Short story, i dont receive any notification that he accepted, he keeps insisting that he did. Then he tries to do a direct transaction which i reffuse so he proceeds and bans me from discord.
Whie we were having this conversation, there was a message that i could not send because he removed me from friends, i suspect he tried to block another person he was talking too but he accidently removed me.
