Avoid in my opinion, rampant cheating now.
I have played since beta, many of the players that I knew over the years have quit yet their accounts are still active/renamed. Even players who have outright stated they now control x y or z account (and proven it). Reporting them has achieved nothing, every single one.
Between alts and scripts/auto clickers, good luck being competitive unless you are willing to do the same.
I suspect Inno Games either no longer cares or is turning a blind eye to players that actually spend money
