I’d suggest everyone use the open(abbreviated name)rp or open(name)rp as it will be far easier to find other indies and not spam. That being said, people still use the (name) rp or (abbreviated name) rp depending on the fandom.  You can also find people in the (name) indie/open rp or indie/open (name) rp too.
