I am experiencing this too, it is so annoying and getting on my nerves. I get up to 4 messages from them claiming to be from one company or the other, asking me to message them on telegram or WhatsApp. I do tell them I'm not interested.
But it is annoying, because as a new seller, I am always looking forward to my first messages and all I got was this spam message from these spammers. It's annoying and disappointing at the same time!
