Hey! So for how to ban someone on roblox, you gotta use the *Ban* function in the game settings, not just kick. Kicking just removes them temporarily.
If you're using a script, you can do something like:
```lua
game.Players.PlayerAdded:Connect(function(player)
if table.find(bannedUsers, player.UserId) then
player:Kick("You're banned!")
end
end)
```
For alts, it’s tricky since they can just make new accounts. Some people use IP bans, but Roblox doesn’t officially support that. Maybe try a plugin like *Banland* to help manage bans better.
