Can I write to Yahoo for some changes I want?

They will not give a damn.

Sounds good to me. Let's start a letter writing campaign 

Yeah...do it.  Also, tell them you want the animated avatars back, as well as the email links restored on profile pages so users can contact one another. 

There is no point since Yahoo! Answers is shutting down in a few days hun.

Please TOS report that troll impersonating me.

Just go straight to the media, as that's how things get done these days. You have to sleep with Mark Zuckerbuerg or Jack Dorsey to keep the story from getting squashed, but you don't have to like it (thank goodness).

Don't hurry. Plenty of time. 

Sure you can. No one is stopping you, not even the trolls. But check your email after 2 secs for mail delivery failed message.

You also need to ask for the crazy chinaman Weedzz to be top moderator

Better do in by the end of Saturday. Engineers are bored to the death on Sundays, hun.

Sadly too late..
