Is it truly obligatory for the P2P sellers to ask for stuff like that? Like, ain't my info going for use on suspicious actions? Idrc about sending it as I am irrelevant nevertheless it has my tackle innit so I'm type of frightened. The seller launched it in the long run though, simply curious if y'all also encountered one. Recognize the answers if there's any.
