The vast majority are spambots who do not reread the thread they started or posted into and rely on folks clicking on the links embedded in their posts.
In fairness, minidik always posts 'car' as a mini variant and so easier to spot from an admin perspective. Usernames generally have upper case characters scattered like a mad dogs poo throughout the username. They also like to use any and all ways to get links posted and so have all the contact icons activated in their profile.
When I see them on the several visits I have here each day I simply ban them out of hand, irrespective of whether they posted or not.
It's also interesting to see their location as USA somewhere, ip as Far East/china and email as Poland, Russia or whatever. Those ones get binned out of hand as well!
As to replying or not? Would suggest not replying or pressing the clipe button. We will get them in any event.
