After three days of use
ltc.pool.grewe.ca i got nothing. At last night this server was fell and his owner (TheSerapher) say:
"...Since my machine running this pool is rather small I was not able to create backups for all our shares. Those have been lost in the recovery process. All other information was restored and you should be able to mine as usual."
Support doesnt answer, i use Contact form from the pool server.
I think, ltc.pool.grewe.ca - cheat-mining server, coz couple minute before server is fell, i receive notification mail "One of your workers is currently IDLE".
Ok, not so smart for TheSerapher, but i find on the page (
https://litecoin.info/Mining_pool_comparison) other pool:
ltcpool.nl - possible scam, is fell today too, but i doesnt get any email notification before falling.
