Any group that goes afk grows with time. Its called making babies.

They disappear and teleport back. They are wizards aren't they supposed to do that?? :/

Similar kde - An average thirst for interest. Keeps them right on the border of being too boring and too adventurous.
All their levels range from 42-48 - Similar educational level. Either UG or UG+PG.
Same set of gears and low level pets - The cars they drive are all ****ty Honda Civics no matter how much they earn and they all wear the same clothes.
Randomised clothing to hide shady stuff - Their dressing sense is pathetic and everyone knows it.

I think they are just some Indian dads who work in IT. Leave them be before they get you arranged married.
