I tried LeechBlock for a while and had that 64-char random string passphrase thing on. Turns out I became really quick at typing those 64 characters to get my dopamine fix.

Things like the OP and LeechBlock are tools for people who have already mostly conquered their addiction, to help keep them from relapsing. On their own, they're not sufficient to turn an addict into a non-addict.
Because I am not always driven to type 128 random characters or even use my phone camera, so it does successfully stop me from procrastinating much of the time.
