"Wеlсоmе to Јоіn Us as Еԁіtorial Вoаrԁ МеmƄеrs/Ɍҽνiҽwers" is always the case. I got the email from Duncan Athena again for joining their Earth Science. However, this always looks very suspicious since the "Editorial Board Member and Reviewer" are always with strange letters.

I think this is a kind of technics to avoid legal issues. If you join their Еԁіtorial Вoаrԁ МеmƄеrs, they can claim it's not a "member" but a "МеmƄеrs" they invented. Therefore, you will do the same job as an "Editorial Board Member" but you can not be really entitled to an "Editorial Board Member". Otherwise, why should they use other letters/alphabets?
