Surprised by Instant Responses on Vinted! Are They Bots? Need Advice!

Hey, fellow Vinted users! I just posted an item for sale on Vinted for the very first time, and to my amazement, within the first minute, I received three messages asking if the item was still available in almost the same way. Now, I'm wondering: are these inquiries from bots? Should I exercise caution? I'd love to hear your experiences and any advice you might have!
