I always get paranoid about these things ever since the Streisand Effect became a thing, I feel like the outcome is you enter a second list and this second list is maybe less friendly as it turns you into an outlier which brings other kinds of problems

No, the system is rigged in a different way. There is an actual data broker industry that's mostly hidden from view; and then there are hundreds upon hundreds of ephemeral "look up your neighbor" websites that you know about and end up submitting opt outs to, only for half of these websites to disappear and a new crop to show up in a year or two.
