I retrieved and old database I had, including all profiles at end of November 2018. Acording to what you say, the profile you are looking for should have:
-   Been created before end of 2010
-   Last active before end of 2011, to allow for a margin (not up-to-date, but a November 2018 snapshot serves the porpose).

That renders a list of 384 potential profile candidates:

I have provided the bare amount of information in the list.
