@HistoPol @osc this doesn’t even begin to address how using mastodon has any way changed regarding your PII since Threads joined, nor how blocking them will change anything.
Because this fails to address how all the data you post on mastodon is already public, and what more is gaining (from you, not from its users) by joining the fedi with an app.
If mastodon users are not-infosec-savy, they are *already* into trouble, they were the instant they joined mastodon.
