Has anyone else noticed this? I wonder if it's a new form of spam that has snuck onto the site. When I post long texts, a handful of random words show up as hyperlinked. I've only followed one, and it led to a generic ad site. Any way to fix this?

I believe the problem isn't on the site. An adware must have infected your computer. Sometimes when you install a software there're adwares that are installed together if you choose the typical install (always choose "custom install - you can see what is being installed and accept or reject it). They can show as a toolbar in your browser, but sometimes they don't show at all. Adwares often do what you are describing.

I suggest you check your computer for virus, adware and spyware. There're free softwares and online scans that can find these malwares and get rid of them.
