Popular Twitch streamer 'Alinity' recently attempted to copyright strike the most subscribed YouTuber, PewDiePie, after he used he called her a "thot", and she hasn't stopped there.
The video in question from PewDiePie remains live, so as far as we can tell her attempted strike was unsuccessful, but it turns out that it was not only PewDiePie's video which Alinity targeted.
Shortly after the news spread of Alinity copyright strike witch hunt broke, numerous channels, a lot smaller than PewDiePie's, received claims on their own videos - many of which simply reporting on the situation.
This was picked up by YouTube 'news' channel Scarce, who reported that a number of small channels had reported to him that claims were being made on their videos - manually by Alinity's agency.
Scarce shows one such example, from a YouTube channel called 'L of The Day', which Alinity manually claimed, and as such is now receiving any ad revenue from.

As Scarce explains, for many small channels it is much harder to fight back against copyright claims of this kind, as YouTube will often not intervene given the large volume of strikes made daily.
It is unclear whether or not the copyright claims are justified, as fair use on YouTube does allow for satirical and reaction based commentary and critical discussion of other peoples content.
These videos simply report on the incident between Alinity and PewDiePie, therefore presumably would fall under fair use.
