Taken from GM-Site:

Friends, it sometimes happens that a result of over 1,5 years of hard work with almost no day offs could be killed with just one push of a button.

It seems that Steam doesn't like when someone provides a great service. Maybe they got jealous, or maybe they don't like the fact that because of GameMiner a huge amount of people in RU/CIS territories learned about Steam and began to use a legal digital game distribution service. I don't know.

The fact is: today Steam has locked all our accounts. Gift receiving account, gift sending account, account for all those gifts from crates (where most of our profits went). They locked even my personal account.

At the moment we have stopped accepting gifts. Of course we immediately wrote to every possible addresses, trying to reach Valve people including Gaben. We will wait for their response.

But if this is a witch hunt – sadly GameMiner as you know and love it will cease to exist. Next several days will show us what to expect.

It pains us the most that we've already had so much great plans (and we've already invested our profits in them).

Our huge re-design update should have raised our content and usability to an out-of-reach level. Also, we have planned to help indie devs to promote their games or to help them pass greenlight. All this free of charge.
Also we’ve been working with some key stores so they would give away hot releases for you in exchange for some ad space. And so on.

It will be a pity if all our efforts just disappear.

So what now, PB/Gala and SG is next?
