Last year many artists were hit with what were assumed to be troll/fake DMCA notices on twitter, patreon and other websites and were urged to dispute them as such. Well, at least one of those counter-notices has been responded to and posted: from Nintendo's lawyers, the same ones they send after fan games/mods like Pixelmon.

The targets seem *mostly* limited to people making money off it- patreon, redbubble, teepublic, and private websites- but twitter posts which of course receive no revenue or compensation have also been targeted.
