StackExchange has imposed a code of conduct saying that participants have to refer to each other person by per specified pronouns.

Paraphrasing to avoid pronouns is forbidden; people are required to get practice using all sorts of pronouns.

The rule was received with tremendous hostility. I have never used in StackExchange and wasn't thinking of doing so. (Too busy, in any case.) I don't even know whether it is possible to post on the site without running nonfree Javascript software — if it isn't, I urge you to reject posting there, for your freedom's sake.

But I reject the demand to speak or write with singular "they". I have a better system for gender-neutrality in English, and I will use that.

I hope others will take it up; I suggest you consider it. But I don't claim the power to demand you use it.

If you do participate in StackExchange, you might choose unusual pronouns for yourself. Not absurd ones, or nasty ones, just unusual.
