At least within HoloPro, most of the past graduations/terminations came out of no where with no chance of doomposting. Just look Sana, Coco, Rushia (I don't think as many people expect Cover to just straight-out fire their top earner), Aloe and Kaoru.
On the other hand, look at Gura with all the constant doomposting about how she is going to graduate.
Mister you forgot that Rushia got investigated and Aloe got suspended before their respectives fates
My point was that not that many people were doomposting about them, they were definitely expecting them to return after their respective "break".
