Blocking Someone By Tag

Recently, I accidentally misclicked and unblocked a Guy-Who-Was-Not-So-Good-To-Me™ on Discord, and I had already removed him from my Recent DMs list; so, now, there isn't a way to block him since we do not share any servers.

Personally, I think it would save a lot of trouble if a feature of blocking someone by their Discord tag is added, especially to those who want to block problematic people prior to any interaction, and to those who accidentally unblock people. (like ME! god im such a boomer)
