Because I moderate comments (though very loosely as described here), I get very little comment spam (a couple a day), as people try to find some usually older post to try and get one in, at which point they open the floodgates (last time it happened, I started getting hundreds a day). It’s annoying but manageable.
The topics tend to rotate. For a while, it was selling term papers to college students. Recently, it’s been about small business loans. Really boring stuff.
Recently, I got one on one of my CQRS posts:
This is all good advice for purchasing a "used car." However, I would like to add that buying a car "sight unseen" could be risky since you are only seeing a couple of photos and a description of what the buyer's version of the "quality" of the car they are trying to "unload."
Not exactly what you might consider on-topic. Best thing about it? It was for a backgammon site.
Nice.
