Well how shitty does this forum have to get before heavy-handed measures become necessary?   I would suggest that the benefits of a measure like this would outweigh any inconveniences experienced by some noobs who are in all likelihood alt accounts anyway.  It's not a perfect solution, but it's worth trying.  It's better than doing nothing.  If you keep doing nothing, bitcointalk might as well start up a local board for English.  Drives me nuts when proposals get shot down because they're not perfect.  Nothing is.
