We talked with Alenanno in chat (and see also the discussion here) and we agreed that some tags cover intersecting sets of questions. Here they are:
english-to-russian and translation: we want to keep translation, because it is more general and because, if I understand correctly, this site is not for russian-to-english translation.
swearing and mat: we want to keep swearing
terms and terminology: we want to keep terminology, nobody's using terms
Also, I think that tag inclination was created to denote declension, and it would be nice to keep the latter and remove the former.
Is it possible to remove english-to-russian, mat and terms?
