Coinotron are asking miners to leave to fix the 51% threat. Ghash had a similar situation a few months ago as well. Saw this on Reddit:
"Due to the Litecoin hashrate increase on the Coinotron mining pool, the cryptocurrency silver is now under the 51% threat.
Ghash.IO mining pool welcomes all the Litecoin miners to join our pool with the 0% pool fee and enjoy unique advantage of shared credentials with CEX.IO Bitcoin Crypto Exchange.
We encourage media resources and Litecoin adherents to help us in spreading the following message and save Litecoin together.”
link?
Coinotron did NOT ASK anyone to leave.
Ghash.IO is just trying to get miners to move to their pool.
Yes they may be of course they want more business, but all should be concerned about 51% situation on LTC.
Plus you are wrong in saying they are not asking miners to leave. Coinotron ARE asking miners to leave (just not doing a good job of it) read the Coinotron comments here on bitcointalk
