Why is this script on this simple grass model? is it malicious?

Help

the model is 🌿 Grass Field Meadow Lawn Pasture Nature Groun (https://create.roblox.com/store/asset/113178278908579/Grass-Field-Meadow-Lawn-Pasture-Nature-Groun) By @szamareks99 (https://www.roblox.com/users/9254722424/profile)

Im totally new and was watching out for suspicious scrips attached to models. the script is as follows:

-- Created by Quenty (@Quenty, follow me on twitter). -- Should work with only ONE copy, seamlessly with weapons, trains, et cetera. -- Parts should be ANCHORED before use. It will, however, store relatives values and so when tools are reparented, it'll fix them. --[[ INSTRUCTIONS

  • Place in the model

  • Make sure model is anchored

  • That's it. It will weld the model and all children. THIS SCRIPT SHOULD BE USED ONLY BY ITSELF. THE MODEL SHOULD BE ANCHORED. THIS SCRIPT SHOULD BE USED ONLY BY ITSELF. THE MODEL SHOULD BE ANCHORED. THIS SCRIPT SHOULD BE USED ONLY BY ITSELF. THE MODEL SHOULD BE ANCHORED. THIS SCRIPT SHOULD BE USED ONLY BY ITSELF. THE MODEL SHOULD BE ANCHORED. THIS SCRIPT SHOULD BE USED ONLY BY ITSELF. THE MODEL SHOULD BE ANCHORED. THIS SCRIPT SHOULD BE USED ONLY BY ITSELF. THE MODEL SHOULD BE ANCHORED. THIS SCRIPT SHOULD BE USED ONLY BY ITSELF. THE MODEL SHOULD BE ANCHORED. THIS SCRIPT SHOULD BE USED ONLY BY ITSELF. THE MODEL SHOULD BE ANCHORED. This script is designed to be used is a regular script. In a local script it will weld, but it will not attempt to handle ancestory changes. ]] --[[ DOCUMENTATION

  • Will work in tools. If ran more than once it will not create more than one weld. This is especially useful for tools that are dropped and then picked up again.

  • Will work in PBS servers

  • Will work as long as it starts out with the part anchored

  • Stores the relative CFrame as a CFrame value

  • Takes careful measure to reduce lag by not having a joint set off or affected by the parts offset from origin

  • Utilizes a recursive algorith to find all parts in the model

  • Will reweld on script reparent if the script is initially parented to a tool.

  • Welds as fast as possible ]] -- qPerfectionWeld.lua -- Created 10/6/2014 -- Author: Quenty -- Version 1.0.3 -- Updated 10/14/2014 - Updated to 1.0.1 --- Bug fix with existing ROBLOX welds ?
