I've just received one of those 'ᴏᴜʀ ᴀᴜᴛᴏᴍᴀᴛᴇᴅ ꜱʏꜱᴛᴇᴍꜱ ᴅᴇᴛᴇᴄᴛᴇᴅ ᴀ ᴍɪɴᴏʀ ɪʀʀᴇɢᴜʟᴀʀɪᴛʏ ᴡɪᴛʜ ʏᴏᴜʀ ᴀᴄᴄᴏᴜɴᴛ ᴀᴄᴛɪᴠɪᴛʏ. ᴛᴏ ʀᴇꜱᴛᴏʀᴇ ꜰᴜʟʟ ᴠɪsɪʙɪʟɪᴛʏ ᴀɴᴅ ᴀᴄᴄᴇꜱꜱ, ᴘʟᴇᴀꜱᴇ ᴄᴏᴍᴘʟᴇᴛᴇ ᴛʜᴇ ᴠᴇʀɪꜰɪᴄᴀᴛɪᴏɴ ᴘʀᴏᴄᴇꜱꜱ.' messages. If you see one of these, it is DEFINITELY a #phishing attack. Mastodon does not have 'automated systems' to do this. You should report it immediately. Edited: and immediately after, I received a second, identical. Looking at the bot activity, it's targetting pro #Palestine activists.
