CheckFeminine flagged "ты заплатил за домен" as a masculine self-reference.
The second pass reads a masculine past-tense verb before "тебе", "тебя" or
"за" as her speaking with the pronoun dropped, and it checked neither the
subject nor what "за" pointed at. He is male, so a verb governed by "ты"
must be masculine, and "за домен" is a price rather than a favour.

The talk fixture was under-reporting by a point whenever a reply addressed
him in the past tense, which is common.
