Old username still linked to account?

[PreyToGod]

Hi all,

As title states, I've noticed that when inputting my old username into google search, it crawls the net and displays this account , even after several username changes.

I've used this username for a few other things and for obvious reasons, i'd prefer for it not to be linked to them.

Is there anything I can do to resolve this issue? Would nuking the account eventually stop it from being indexed?

Thanks in advance

I don’t think nuking this account would help as we are not feeding the old username to google. The trick will be to somehow get google to update their index which I am not sure how to do.
