I was playing on a server when I went through a nether portal and got stuck
I joined another server but then when I jumped I would start going up and down
Same thing would happen if I got on a block like bamboo
(Servers that I mean)

Thank you for your report!
However, this issue is Invalid.
Unfortunately we don't accept issues related to External Servers here on the bug tracker, but please add more details if you think this also affects multiplayer over Realms, LAN, or XBL.
I'd suggest contacting the server owner directly or seeking help on the Minecraft forums.
