I read recently all kind of complaints about them, on steemit, but I didn't think they are that bad. I had good enough experience with them.
I managed to withdraw some but last week I got 2500 steem blocked there. I wrote one post one week, yesterday another one, and I'm going to to do it on weekly bases to warn people until they fix the issue. I understand sometimes they have to do it, but doing it for weeks is totally not acceptable.
Today I just published my post celebrating my reputation getting to 50. I mentioned your post there along with my lesson learned, as this is practically my success recipe.
