If the person who shared the text message shared with us through social media sites deletes it immediately

we will not be able to see it, but we will be eager to see it, there will definitely be a debate here as to whether this is right or wrong because it contains so much information that each application company has its own set of policies for that

It is therefore not allowed to view the deleted message, however people do it for their own needs, see some help and some discussion on this.
