Gatherer + Routes + script

I want to use Gatherer and Routes to "draw" on my minimap the best possible routes for farming herbs and mining. Also, there's a script that automatically changes "Find Herbs/Find Minerals" every 2 seconds since i have both Herbalism and Minning on my character. Now I'm not sure i can use it since a saw a bunch of accounts banned for using scripts. Would my situation be a reason for a ban?
The script is:

/run if not THO then local f,t,c=CreateFrame("Frame","THO"),1,0 f:SetScript("OnUpdate", function(_, e) c=c+e if c>3 then c=0 SetTracking(t) if t==1 then t=2 else t=1 end end end) THO:Hide() end
/run if THO:IsVisible() then THO:Hide() else THO:Show() end

You shouldn't have problems with something like that.
Scripting usually reffers to lua or third-party software which automate your gameplay - will be tracking ingame combat events and respond to them like
Enemy trinket > Script use Blind ability instantly

Oh, cool. Tnx a lot for the info
