Is my use of "oblivious" wrong?

Solution 1:

I have deliberately omitted @ referencing the author of the comment, but his standing in this community is not oblivious to me.

I am trying to say that I am aware of his standing in the community.

In that case you are using the wrong word. Here's a possibility:

His standing in this community is not unknown to me.

or

His standing in this community is not unfamiliar to me.

P.S.

If you still wish to use the word oblivious then you could say, "I am not oblivious to his standing in this community." A person can be oblivious but an inanimate object or an abstract entity cannot.
