I told all my frustration about this approach, threatened to start litigation again them (we have consumer rights protection bureau in Latvia, which solves small cases for free and with little paperwork)! They re-enabled my sites, but with limited resources. If you see some error messages, blame only this greedy hoster!
Unfortunately I have little free time right now to move sites to the another server, but will do this certainly when be free (I hope VPS node I own is powerful enough to handle also Daily Bitcoins).
Few minutes ago I contacted the admin again, he promised to add more server resources to my sites tomorrow.
Take this accident into account if you ever decide to deal with the hosting provider "Nano.lv"!
Lol they disabled your account.
