Boycotts don't work unless they know it

This is in reference to Twitter, and the NAACP and other groups calling for a boycott of advertisers.
If companies are supposed to wait until they see a small drop in sales and assume that it may be related to their Twitter ads, the boycott won’t be effective.
Instead, keep a template to cut and paste for companies you see on there and send an email to their PR or Marketing department. A suggestion:

“My spouse and I are planning to buy new (xxx) this month. We are honoring the general boycott of Twitter advertisers until the site establishes sensible content moderation and won’t be considering (your company). If you decide to withdraw your Twitter ads, please let me know so I can consider your product again.”

1. Bonus points if you can get a screenshot of their ad next to some vile tweet, and tell them

that you are so very disappointed that they would associate with such awful behavior.

2. I had a friend who was Manager of a restaurant

He said the owner looked at Yelp and Google reviews daily, but his rule of thumb was that a negative email or text sent directly to them represented at least 100 other people who had the same concern.
I often get replies back if I complain to a company about where they are advertising.
