Ok I need help with youtube.

What exactly do আপনি mean দ্বারা "spammed"? As if আপনি got a মতামত on a video that was spam, অথবা one of your মতামত was marked as spam?
Either way it's not a bad thing. Just try not to মতামত spammy kind of things and you'll be fine. ^^

Well, Hurry and remove that মতামত before everything get's bad!
