How does stack exchange identify if someone is inflating his/her own reputations?
On the other day, my other account was been banned for a week because my friend gave me a vote up on my all questions and answers.
Isnt it legal?

No, its against their CoC.
The complete how its detected is keep in secret, but for sure we know that for one account that target another account for upvoting or downvoting will get tagged by the system. Same with the localisation.
The goal of such action from SE is to prevent voting fraud. As if everyone could be able to do that the point system will loose it’s usefulness, it would be unbalanced and would mean nothing in the long term.
Imaging too if someone hate you and start downvoting everything from you, the system prevent such bulk action too.
