why some casinos hide bonuses if your account is too old.

Noticed this a while back - sign-up promos and deposit bonuses seem to vanish if you’ve had your account for a few years. I get it, new players need bait, but sometimes they even hide recurring offers or reloads for long-term members. I check bonus pages regularly and half the time stuff is just gone, but friends with new accounts see it.

Seems a bit off, especially when the regulars are the ones playing steady. Maybe it’s some algorithm or just a way to keep churn going, I don’t know. Wondering what’s everyone’s experience?
