I agree that we're only partially solving the problem that comments were designed to solve by locking them up at 50 rep, or any level, because those who can't use them will continue to exhibit the behavior that they're designed to _stop_. 

I don't want to put additional needless asks on people that spend a lot of time in review; indicating if a string that is often too short to be an answer is good or not good is just a waste of people's time. That would be turning /review into more of an unpaid Mechanical Turk than anything, I know this because I've spent _years_ looking at comments left by new users that managed to earn 50 rep.

What I propose is simplifying it. Let _anyone_ with a registered account leave a comment until ***n*** comments left by them have been flagged _and_ deleted. If that happens, back to waiting for 50 rep they go. I know this is a little complicated, but enabling this softens one of the first sharp edges folks hit when deciding to engage.

Anything else I fear is going to require a hard look at our comment system and the tools available to moderate them (which, quite frankly, stink). I really think we should be looking at ways to _reduce_ the amount of work comments create. While your idea would work, I feel very awkward about the ask involved with putting them through /review.

As for ***n*** - it would need to be quite low, as in 2 or maybe 3. _Most_ people that would get access to this would end up being blocked until 50 rep anyway, and we need to be good with that. What this opens for is that occasional [_pearl_][1] that wants to engage and knows how to do so effectively.
