FanDuel loss limits real?

I keep seeing people saying there’s a hard loss cap on certain big sportsbook apps, but I’ve never actually seen one get enforced personally. I’m the type that sets my own limits and sticks to crypto sites more than the mainstream options, but I’ve tested a few of the bigger names out of curiosity. Has anyone ever been genuinely blocked or limited from depositing just because they hit a supposed daily or weekly loss threshold? The sites advertise these “protections” but I wonder if it’s more PR than reality.

Feels like unless you contact support and ask for help, the system just keeps letting you reload. Curious what the actual experience is.
