A repair suggestion for Minecraft Bedrock Edition Multiplayer

I'm an creator of minecraft bedrock addons

Nearly I found that a group of spam bots from "Lumine Proxy" attacked the multiplayer world of mine and my friends

I tried to catch datas from these bots:

Bot Connected->AsyncPlayerJoin Triggered
callback:{name:[random string],pfid:""}
access denied (if allows them this time,the bots count not be kicked, joined as name `§"`)

Bot Connected again->AsyncPlayerJoin Triggered
callback:{name:[real xbox account name],pfid:[real pfid]}

Join allowed

then PlayerJoinAfterEvent triggered and PlayerSpawnAfterEvent not triggered

bot  start to spam as "* External"

Solution Suggestion:

• Players who are not allowed to join but have not been generated cannot send messages
• Add MessageReceiveBeforeEvent to allow creators cancel "/me" message from websocket

* If this problem is not resolved, it may cause a large loss of players.
