does using faucet/free coins before depositing make crypto casinos review you harder

So I’ve been messing around with the daily faucet and free coin spins before I actually deposit, just to get a feel for the site. Not talking huge wins or anything, just grinding up a couple bucks before putting in real funds. I keep seeing these posts warning that doing this can flag your account or get you reviewed harder when you cash out, but no one really gives specifics. It sounds pretty tinfoil hat, but also… I wouldn’t put it past some sites.

Does anyone have any real experience with this, like were your withdrawals slowed or did you get asked for extra KYC after using the faucet before depositing?
