Isn't Isekai a fantasy trope about modern people getting 'transported' into another world? It's not intrinsically linked to reincarnation. It's more like strong escapism.
Yeah, I read somewhere that the reason for banning it was due to a trend among Russian teenagers; they would commit suicide in the hopes of going to a different world. As such, the ideas shown in such anime (escapism through death) were deemed harmful and banned.
