Tabs vanishing over time

Ok so this has been bugging me for a while now. Has anyone else noticed how some tabs seem to have somehow disappeared over the course of time? I’ve just been playing this one from JordanVS and was pretty sure that there was an another version from Kabukibear at some point - and after a quick search sure enough there was one at some point.

There was also a Fingerstyle “Dead Sea” tab from Chrono Cross at some point which has been gone for years now. Does anyone know what’s up with that? Is it intentional because the tabbers took them down themselves or did they just vanish into the depth of the system? I’m sure there are more but these are just the couple I’ve noticed.

Some people do choose to take them down. But it is possible they could vanish for other reasons that we don’t know about yet. And if they do I really would like to know about it…
