Its depends on how long the Script will stay UD, before the first banwave back in early late march/early april i played the same account for nearly 2 years with 2 diffenrent scripts from MH.
it always depends also on wich elo u are, Low Elo u will probaly not getting bannend for months High-Elo if ur unlucky u get bannend fast bc Riot employers look manuell sometimes at reports.
I say it everytime again, if u move like a bot but dodges everything u will get called fast when someone already had many scripters in there team or enemy team.
Good movement + Positioning it could take a very long time until someone calls/getting banned
