Attainability delusion

When a streamer's audience (usually male) fool themselves into thinking the streamer (usually female) can be attained for a relationship as long as she is single. This delusion is shattered when she reveals she is in a relationship, which, consequently, leads to indignant backlash by the horde of disappointed men.
Streamer: I have a boyfriend, guys!
Delusional man: Ohmahgerd but I thought you were mine.
Streamer: Sorry to shatter your attainability delusion, but you should've known better.
Delusional man: *proceeds to report all her accounts*
