This person is having fake alt accounts and keeps requesting to join party with his other...

Yeah, can take something until enforcement team can review their account activity

Also, could be good change your privacy settings to avoid future inconveniences

Hope you're doing great today mate

I am sorry to hear about this, rest assured that Xbox Community does not support such behavior which is why we are best to advise to report so their Enforcement team can conduct an investigation and apply proper Enforcement action once proven guilty.

Yo thanks I don’t like what people do it’s annoying It’s probably what they do with decoy accounts Hope u have a nice day

A guy keeps on treatening me saying he will boot me offline and fry my AC, i blocked this person but he keeps going on alt accounts and telling me to unblock his main account and message him i dont know what to do please help.

As long as he doesn’t join the same party that you are in, he won’t be able to boot you offline as that’s the only way for someone to grab your IP address.

Unless you were in a party with him, he should not have your IP address and won’t be able to do anything at all except harassing you through messages.

For now just ignore them. Eventually they should get tired of it and leave you alone.

If you're getting disconnected regularly and you know it's going to be a dedicate effort for a while to come, don't enter any direct communication with that person (or a random person who could be them) and change your IP address, if it's possible. Some
IPs will change automatically but some don't.

.

If your IP changes or you change it, they won't be sending the fake packets anywhere meaningful (or hopefully not ) and you won't be disconnected. Don't join their party and don't join their game... messaging is fine, but don't join a party. As soon as
you're in the same game or party they'll have your IP address.
