Minecraft servers are changing?

Hi today I sorted my Minecraft server list when I later clicked on multiplayer again but the servers that I had packed up (gommehd and hypixel) to the servers introuble and thevance have become the others

Were just gone. Does anyone know why?

Have you installed any clients or mods?

It is possible that you have a virus or have been hacked. Only worry about it if, strangely enough, programs are opened, your mouse is shaking or something like that. Did you install something recently?

It's been like that for a long time

Esdeath Labymod and bac is already like that in the normal mc
