My guess is that 50% of the coins in maintenance have a dead network.. The other 50% need desperate attention though.. Maybe it's time to teach your moderators how to stop/addnodes/start a daemon Blacksmith

Just my 2 satoshi..
In the case of Pesobit,
it's complete negligence on their part. The Pesobit network has been very alive since the beginning with many nodes

The problem we had is a hard fork
7 months ago,
and they never updated to the new fork. Pesobit now trades at C-Cex with nice volume every day,because they updated to new fork.
We warned Yobit countless times about this, not even one answer. I mean come on - coins have hard forks from time to time, it's not unusual. Now a few people are stuck with coin here, at Yobit.
they dont process active coins like dime im aproaching 2 weeks now what do you espect them to do with the ones in maintainance? well i come here and ask again sice noone replied to my question properly. does anyone have or had frozen withdrawals for active coins for more then 30 days?
