There was a time about 30 to 40 years ago where an entire congregation would be encouraged to love bomb a newly interested person. My father forced me to do so while I was growing up. This often made me feel uncomfortable. Things did change. It did get to the point that the love bombing circle shrank just to the person who was studying with the newly interest person.
You are also correct - once that new person is baptized they often soon found themselves alone. They might be able to engage in conversation before or after the weekly meetings at the Kingdom Hall. They invites to people's homes or other social events would soon disappear after baptism.
I do recall many new converts disappearing within a year of baptism. What do you expect when they are told to cut all ties with non-Witnesses and then they are starved for social interaction after baptism?
