Uptick in abandoned offers?

Sellers: I don’t understand why, but I’m getting a BUNCH of offers, which are reasonable, so I accept, and then they ghost. I’ve been selling for a few months now and never had an issue until this weekend. It’s not looking like spam accounts or anything either. A lot from people who sell!
I’ve abandoned a couple offers before but I tell the seller why and reject so it’s not hanging out in their messages as a pending offer. I try to be conscientious for sellers because I know a lot of people cross list like I do. Curious if anyone else has noticed it?
