I've seen it advised here that in lieu of deactivating your account on the bird site, instead set it to private and simply don't visit anymore.
If I understand correctly, deactivating means that your old handle there can be recycled/repurposed by someone else.
And setting your profile private should mean that your existing posts there aren't able to be used by outside interests.
Just a thought.

I took that approach over there.
