The TM30 still isn't an issue for everyone. It was in 2019 that the TM30 insanity reached its peak, but has improved since then. Each office is different. For anyone NOT on an extension of stay, the TM30 has never been an issue.
Being pulled aside, if you're on an education visa but don't attend classes, or visa exempt/tourist visa and using these too many times in a relatively short period of time (especially the former) and particularly if combined with 30 day extensions obtained at immigration offices has been an ongoing issue since roughly 2014. Back in the day, reports of being pulled aside were just occasional, but from late 2015 they were increased and have become noticeably common this year.
