Just a heads up, getting a bunch of scam replies to my WTB posts (some requests almost a year old).
The person will have just joined, have 0 posts and send you a message stating "You can contact [so-and-so] he has [whatever part], here is [so-and-so] email ... [some gmail address].
Might not be new to you (and might be old news), but has been very frequent as of late for me and not unlike a bunch of Ham Radio forums I frequent. They will pull the cashapp/moneygram request.
I played along with one for a while just because, he was happy to send me multiple ground control kits over night for $150 - go figger.
