All artists are credited if known — and most are, if only because they've signed their work. It's hard to imagine MOBA doing otherwise — they're already copying without permission (I assume), and deliberately suppressing artist identities while ridiculing their copied works would be gauche even if legally defensible as satire.
MOBA's schtick is to present these works as alternatives to "important" art, which is cool. But they just can't help themselves and lay on the snark heavy and thick.
