I'd heavily discourage people from trying to get around blocks/find out exactly who is blocking you*, because I don't think it's a terribly healthy thing to do for oneself—not to mention disrespectful of the blocker's boundaries, and makes them even less likely to change their view of you—but if it's just to view posts, logging out would have the same effect and be a lot more convenient.A block would give a two way total censor, but that may encourage someone to make another account to see whatever, which more than one account is something the staff doesn't like.
Of course, if they're actively trying to block evade and contact the person who'd blocked them, then we'd have the potential issue of users creating multiple accounts as you mentioned. Most sites that have total blocks also have strict rules against block evasion, which could be something staff could implement as an extra deterrent against multiple accounts if they added a full block feature.
*using the general you here ofc!
