I have rolled with people who do things that while they wouldn't work in a tournament or on someone else but work with me. And, I wouldn't call them jerk moves.
For instance, in the past I had loads of dental work so at the time I would tap to face pressure pretty quickly. The people I rolled with often knew this so it didn't come up much. But... when I trained with someone who applied loads of face pressure I would then tap - no problem for me. When I rolled with them, I worked on avoiding those positions. If someone really wanted to tap me on face pressure then they were welcome to go for it. I am pretty sure they were getting nothing out of what they were learning but I was not getting hurt and I was still learning plenty by working on how to avoid that position in the first place.
To me the real jerk move is not stopping something after someone taps. That has happened to me and that is a jerk move.
The other jerk move to me is going for a submission 100% when just rolling, especially something like the Kimura where their is a real possibility of injury. I'll take some gi burn or a sore neck over this any day.
