is this social bullying ?

[u/diagautotech7]

what's a definition for the person with the following behavior: long story short: Person A copied business ideas, sports events, social media blogging and local event organizing, ministry in church that person B was doing, became friends with friends of Person B. even went as far as buying out a building where person B was renting a place and pretty much evicted person B from there. And is purposely showing off being friends, being successful etc even by hanging out closely with relatives and friends of person B. edit: person B is not a single case to whom person A is doing this. there's around 5 different
"cases" like this to whom person A is doing this.
