Can anyone explain to me what these posts are about? https://www.mu-43.com/f93/olympus-m-zuiko-14-150mm-micro-4-3-pen-digital-ed-lens-14192/ How are they generated? Do they benefit the site in some way? Is there any way for me to not even see these threads in the recent discussions section? I occasionally click on one thinking that it might be an ad from a forum user. If they generate revenue for this site somehow, that's great. But when I want to be on eBay, I'll be on eBay.
