Spoiler is just an English word, but you explain the Russian one as through it is originally Russian word.

There is a verb 'google' in English and there is no need to explain it.

Also you wrote 'фейк' means 'неправда' or 'ложь'. But actually 'фейк' means a fake or 'подделка', 'неправда' or 'ложь' mean a lie. Ложь and фейк have definitely different meanings even in Russian. They are very similar but you have to feel the difference as a native speaker and as a teacher as well.
