Re: Junk accounts - what is it? Are they a threat? How to get rid of them?
Maybe lets just delete accounts that are not active for, for example, 1 year ?
The final solution to low quality posters question... 
Delete them all! We have established with OP, in another thread, that it's not about banning but rather some form of tagging.
And so... the final solution is now changed to special badges...
I wonder in what colour and where they will be required to wear it...
hmm
maybe a number instead of a nickname...I hope anyone sees the obvious analogy here? Cleansing is never a good way out.
The only reason they can disturb is filling up the database too much, but if Theymos does not have a problem with them, neither do I.
This! 
Basically ends the discussion, at least for me.
