ITT: "Blocking isn't a necessary feature, specifically because I do not get harassed." Also: "Because you COULD just make an alt, take the time to make a fake email, and even potentially be required to have a fake ID in the future, muting and blocking are LITERALLY the same thing"
Any disincentive is one more step some spineless bastard has to go through to harass you, even if there are work arounds.
