A clear change in airfinex's posting pattern.

What are the best ways to know if an account changes hands is it to increase in post quality or to decrease in post quality okay there are two things involved here; although I am not a professional in digging out cases or tacking out profile that wasn't originally from the real owner but this are my thinking. If an account post moderate and later went off for about a year and comes back when their activities resumes it's either such person increase in their post quality or reduces in their post quality.

If the user increases we can easily assume that account has already changed hands and again if the person decreases we are also assuming the account changes  hands as well but to my own opinion the only way to detect or factor out is to check out their common phrase or a word the user often uses when they are posting even though his quality dropped we can say because such person isn't on space for some period probably being engaged with other works or in other fields where such person do not talk about the latest about the forum.

But if such person increases in their post quality then we can say for the period of inactive s/he has been keeping themselves busy with the latest happening, but to know more better is when they don't regularly use their phrase or words in common to them.
