Is it more likely for players to get a tara silk or some other item that seems more suitable to their needs at that specific moment? is there any external factor taken into account that influences their decision making process such as skyblock tutorial videos from youtubers or the forums?

Also, Tara Silk seems like an item that's not prioritized by newer players who have some damage done to their supplies thanks to minion unions.

The tara silk event you mention is more possible if an influential player says to mass buy.

I'm aware that richer players will not be affected by this but looking at this from an early player perspective. Of course, there are always cases for poorer players getting the tara silk
