We're launching a new experiment to help users avoid the spam label.

Should help people who are good faith trying to engage and adjust how they cast.

Reminder, if you're casting in your own home feed, channel or replying to people you who follow you, the spam model doesn't focus on that. 

It's only if you're excessively replying  to people who don't follow you (with no engagement).

I know this is for a small % of users but would be cool to factor in whether or not the person being replied to has seen the reply when deciding to label a reply as “unengaged” (given that so many of these replies from newer accounts are below the fold)
