It has a built-in filter for the poor folks that use these proprietary services like Twitter X, Microsoft GitHub, and Discord Username.
I wouldn’t apply anywhere asking exclusively for these platforms instead of something generic like: instant messaging, public code forge(s), weblog/microblog(s). I would encourage you, reader, to ask around & make sure your org isn’t hiring based on proprietary service usage. Heaven forbid your applicant is from a place under US sanctions & literally couldn’t use the services even if they wanted …or like your candidate has any values about privacy.
