Regarding permanent suspensions for 3rd party software

Hi guys! So i've been seeing alot of perma bans lately, mainly due to 3rd party software used in the LoL client. On my main account I've used such software before (almost 2 years ago now) Is this account in risk of a ban? Or are they only banning people who are using it recently? Thanks!
