I'm sorry to bring this up here, but it's not the first time this happened and I need help to deal with this user.
User:Fitoschido is a very active Spanish translator. Not only he does a lot of work but also it's good work. That works as long as no one else challenges his contributions. In simple terms, he is not a "team player". When you try to contact him and discuss his changes, he doesn't reply or if he does, he doesn't want to reach consensus. It seems that his opinions are the only ones that matters. And this is going on since I came here (3 years ago). Most of the time I try to avoid conflict. I don't want to enter edit wars whith him (or anyone else). I avoid "touching" messages that he translates, etc. I'm not the only one having trouble with him.
But that's not the most serious thing. In the past, he called another users "imbecil" and "stupid". I tried to talk to him, asking to apologise to them so we can have a more pleasant enviroment for all of us (volunteer translator in our spare time) but nothing happened.
All our previous exchange in Translatewiki was in Spanish so I don´t know if the rest would be able to follow what happened, but it's there in his Talk page, in his comments, etc.
Hope someone else here at Translatewiki would help. I want to make clear that this is no personal at all (he makes many and good contributions most of the time) and that what I said is very verifiable in this very site (if you know Spanish).
I suggest talking with other Spanish language translators, and if they make conclusion that that user's certain translation(s) he/she does not "allow to touch" are really incorrect – try to talk them, "finalize" why they are incorrect and try again to correct them – and if that user still does not accept those correct and explained translations, use block on that user for certain periods of time, or indefinitely if still refuses to change (I hope blocking users here is possible same or similar as on Wikipedia).
PS After I posted this answer here, I got notification about New message; this should be fixed so that after user A posts something, user A does not get notification about new comment on some thread. Also, publishing changes when making new post still triggers "Do you want to leave this site, Changes you made may not be saved"...
We use Liquid Threads here for discussion. It is no longer maintained. I am exploring the possibility to move to Flow, which is still maintained. But it won't be easy and migration is likely to be disruptive to some extend so it is not going to happen very soon.
Note: I vote strongly support to migration, because since October, nearly all of my actions are stucked by a huge, huge and huge number of CSRF token errors. Do not say some "wrong from HHVM", HHVM doesn't result any wrong, the only wrong is from LQT which is too hard to uninstall.
