does late regging every mtt close to end make rooms review bonus eligibility?

Been hearing some chatter lately about late regging every single MTT and not really playing through most of the levels, just entering right before registration closes and spinning it up or busting fast. I know a lot of us do this to cut out the grind and just go for max value with less time, but I started wondering if the sites start flagging accounts if it’s every MTT, every day. Especially with bonuses and rakeback stuff, I’m not sure if they want to see that pattern or if it can mess up being eligible for future promos.

A friend of mine claims some sites don't care as long as the rake gets paid, but others track this and will exclude you from leaderboard prizes or limit your bonuses if they think you’re abusing the system. Anyone have actual experience with this or ever get a warning? Trying to figure out if it's really worth the risk to keep doing it this way or just play the regular way for peace of mind.
