"you were less afk..."

i got this message now 3 times in not even 2 months... without having a leavebuster once. how can i "restore my accounts state" 3 times by not afking? i mean THREE times?

i had a leavebuster on january due to some internet problems, i played a ton of games without afking and not even 2 weeks after my first ever leavebuster i got the message saying my account is clean. now i got that message 3 more times in march-april. how/why?

edit: like mentioned, was my first leavebuster. 5x5min
