It would have to be one of three things:
- They had an extremely, extremely poor portfoilo.
- They were part of the collab at one point and were removed because they missed deadlines etc.
- They tried to join the collab during the later stages when they were replacing missing scenes from people who didn't finish their work, when there would've been very few available scenes to do and they just didn't get picked.
Even if it's the third thing, they shouldn't be tweeting shit like that.
