Would not recommend Sync, last update was March 2024 and there’s issues with reporting DMs, cross-posting and more. Just scroll through the community to get a general vibe of the userbase: [email protected].
I personally use Thunder now, and I have used Eternity too. Both support account switching.
I’ve blocked the whole instance ani.social and since then I don’t get softcore anime tits anymore.
Was a tough choice because instances usually host a ton of other communities and users but it just became unbearable like you mentioned.
edit: a side-effect is that users from a blocked instance replying to your comments will not show up in your inbox. Figured I should mention that so you can weigh the pro’s and con’s
