I have been receiveng a HEAVY number of spams, the first ones where too obvious. The last one was kind of rude at first, still I answered, and finally he asked for my email for "more information about the job". I hesitated and this question saved me from making a HUGE mistake.
"I think we can both have an informative conversation through this platform... what can I help you with?" And he never replied.
Tuns out he just started as a buyer on this very month... so yeah... pretty sure he was a scammer.
