Jetpack social plan details + Twitter API Questions

Hi team,

I hope you’re doing great. I have two questions. I’m using the Auto-sharing, (formerly known as Publicize) module and a Jetpack free plan, so I can connect around 150 sites with my WP.com account and use this feature on all my sites (network setup). I see that the shares are now limited to 30 per month as per the article below:

So I might need the Social basic plan: https://jetpack.com/social/

My questions are:

1.- Is it possible to connect my 150 network sites using the same plan (account) for all of them so I can have unlimited shares in all of them? Or the plan is handled on a per-site basis?

2.- Do you use the Twitter API with this module? I’m curious because I found this article, and I wonder if you’ll continue having the Twitter share feature: https://wptavern.com/wordpress-plugin-developers-alerted-ahead-of-twitter-api-changes

Also, the Twitter rules for automated posting mention that it’s mandatory to use the Twitter API because if we use a different method we might be getting our accounts banned permanently:

"Use non-API-based forms of automation, such as scripting the Twitter website. The use of these techniques may result in the permanent suspension of your account."

So would you please let me know if you use the Twitter API, if the automatic share feature for Twitter will remain available, and the social plan details?

Thanks!
