Hello, I noticed you blocked indef this account with summary like "bad translations, after 2 previous blocks". I can totally understand, that english is sometimes better than bad translation, but from my perspective (s)he was actually doing pretty good. I control and correct some of his/her stuff and yes, it is not the best translation I've ever seen, but it is definitely not as harmful to make him eligible for indef block. It definitely is not a machine translation as far as I can tell. (S)he is quite average English talking Czech person from what I can see from his/her contributions and (s)he made a huge amount of work for Czech speaking readers. (S)he also learned from his/her mistakes, I discussed with him/her many issues over the time and (s)he always fixed the issues I've mentioned.
I also noticed his/her talk page is not full of notices about upcoming blocks. In fact, this indef block went without any notice at all, which seems quite suspicious to me. I also haven't found any indication of block request by other persion, which seems even more suspicious to me. Please a) show me some bad translations that made you block him/her indef b) show me the request to block him/her sent to you as an admin by other person. I don't think this is a community induced block as Czech translators I asked seemed pretty happy with his/her work.
