User "system" is causing issues

This appears to be an actual system account, but it appears to be taking over other users’ posts. Example here:

High & Low Octane Gas in Same Car?

I’m about to buy a used car (a 2001 Jetta) and I think the manual says its ok to use 87 octane. However, the previous owner has always used a higher octane gas. Someone told me if I start using lower octane gas it will harm the car. Is that true?

which is showing up in my “latest” feed despite the last post having been in 2007. If you look at System’s post history, it appears to be re-attributing very old posts made by humans to itself - I suspect this re-attribution is why a 10 year old thread is showing up as having had activity.

I noticed that too, said last reply 27 minutes. I almost commented then saw it was 10 years old.
