Thank you for taking it lightly, I appreciate this, too :)

A workout without any true utility to the other party.

Not sure about that :) The utility might not be something material but having beggars in the streets reminds the obeying citizen that not everything is just shiny and nice. Beggars are the reminders of the single souls who might want to escape all misery by banning what disturbs their senses. I must admit though, that if they become equal in numbers with non beggars, it becomes nasty, like you described so vividly. In a way, they show that passive income can be earned "as above, so below". LOL

For the blockchain: there is a lot of tag ignoring also. People "ought to curate manually" but when they are behind in this truly effortful duty, they might receive some complaints. I was pissed myself using tags properly but being neglected for I was probably not a "true community member, lacking engagement" (meaning to make comments of praise to show, that I am "interested in other peoples contents". Which I am often not, if I find nothing of interest there). Instead of making half heartedly comments to please someone, I skip it. HaHa! Consequently I have to endure being ignored myself. Thats the name of the game, right?
