Thanks for your feedback. Unfortunately the spammers like our site and seem to like posting adverts for sunglasses and male enhancement supplements 😂
You'll be asked the questions and a captcha verification for your first five posts, and any PM's you send until you get to 5 posts.
I know it's annoying, but there are only two alternatives; let everyone including the spammers in, or vet every single application. Both involve a lot of work, and since I fund the site from my own pocket, I have to work a day job, so I don't have the time.
I've tweaked the settings slightly, and I'll be keeping an eye on the logs and boards to see what's going on.
