User:Cyphoidbomb/Rudranil Ghosh Vandal

Discovered around 6 March 2018, the vandal started adding Rudranil Ghosh to various Indian films' cast lists. Technically, I probably noticed him a little earlier adding Sabyasaschi Chakrabarty to various Indian film casts, but I didn't make the connection until after I'd dubbed him the Rudranil Ghosh Vandal. He's probably been at this since at least March 2018, based on these.

Methodology: User will pick an Indian actor like Rudranil Ghosh or Sabyasachi Chakrabarty (both Bengali Indians). He'll fluff up their filmography with bogus entries, like here, often claiming that these actors work in a multitude of Indian ethnic/language cinemas, like Telugu, Tamil, Hindi, Kannada, Malayalam, and in some case American films, like The Amazing Spider-Man. In addition to bulking up their filmographies, he'll go to all the other articles and add names and roles to those articles, perhaps to throw off suspicion if someone were to do a lazy check. "Does Rudranil Ghosh's name appear in X article? Yes? OK, must not be vandalism."

Some of the entries might be valid, I have no idea. But the various attempts I've tried to vet their content (especially for something as ludicrous as Spider-Man) I've been unsuccessful.
