Follow up should be on pull request so that they don't reply under issue and get paid for it.
If there isn't a pull request open in time for the warning, automatically disqualify them (they should open a draft pull as soon as they self assign)
Must be configurable since some tasks are not coding related.
If pull isn't required then follow up under issue as we do now.

I think we can also add the point that the activity which should be considered is only the one from the assignees themselves. I believe currently any activity from anyone is considered in the events.
