Then you need extra protection against such an attack. There are many guard mods/plugins that white/blacklist the placing of blocks by block, location, and player.
TMP (turtle motive preventer)- Perhiperal block with stand alone capabilities. By itself, when given a redstone current it creates an 11x11x11 anti-turtle field centered on itself. All turtles that enter this field are stuck, any move, break, or place commands fail.
When connected to a computer, opens an API that gives on/off, range, and whitelist control. Whitelist is populated by tutle ID's that are allowed to move in the field. Range allows the X/Y/Z size of the field to be varried individually (always centered on the block).
