Am I travelling on ESTA too much?

[shawdon2]

This summer I was in the US for 1 month.

Mid-September tlll mid-October this year I was in the US for another month.

I'll be going to the US again this year mid-November till mid-December (3rd month)

Is there a chance I'll get denied entry on my third visit in November? Am I doing anything illegal?

My only reason to visit is for "friends" or "vacation". https://9apps.ooo/

Any tips?
