In an attempt to control the “head spinning” a bit, let me reiterate that in one of the offices at the head immigration office in Denpasar, there is board which tracks deportations from Bali, and the reason for the deportation.
IMHO, experience, and in discussions with others including several consuls representing various foreign governments here in Bali, most all deportations are for very good reasons, and often enough, when visa violations are cited as the reason, it is only because there wasn’t enough proof to arrest and charge the deported “undesirable” for the “real reason” they were booted out. Those other reasons can and often do include well founded suspicions of drug use, prostitution, and pedophilia.
None of what I just wrote should be interpreted as meaning that immigration cannot, or will not, boot someone out solely for a visa violation, as they can, and have, but generally ONLY after the person has been called in for an interview and warned to change their visa in order to comply with their actual activity on Bali.
But yes, it is “sorta right” that it can sometimes add up to who you know just as much as what you know, and longevity counts, meaning the longer one has lived in Bali adds to one’s credibility.
