Enemy Ana said to report me for selling?

Like halfway through the first round they said to report me for selling and I have no clue what that means or why they said it. We were losing terribly, their Genji ended up going like 34/2 killing everyone except me almost instantly, I tried to take them out and only ended up getting them once.

Replay code: CGPS7K

Warning: my gameplay this match was quite terrible, normally I do a lot better.
