Thanks for your suggestions but to be honest, for now I am too lazy to seek for additional explanations online (I consider myself as Steemit user only, who is not full time involved in blockchain related topics - but who is able to understand mathematical topics in general). Because of being too lazy to seek now, I cannot exclude the possibility that you may have a valid point in any way. :)

However based on my (limited) knowledge and mathematical understanding I see no reason why n^2 followed by a linear equation would be more easily exploitable by abusers than n^2 alone (which is what counts in my eyes).
