this garbage has always been an abusive act, and can at best be described as pollution.
all the 'they paid a fee' hurr durr around this is redolent of lolbertarian 'as long as it's private' dribble in the wider world, and just enables more abusive action.
i seem to recall someone posting on here a while back about a block size reduction incentivizing higher fees to combat this, as (apparently) the nature of these inscriptions is hard to technologically defeat - maybe they're right.
