How to post blank comments on YouTube
Posting a blank comment on YouTube is possible using invisible Unicode characters that YouTube treats as valid text. The Braille Blank (U+2800) is the most reliable character — YouTube accepts it in comment fields while rendering it as completely empty.
Simply copy the Braille Blank from our generator, paste it into a YouTube comment field, and submit. Your comment appears in the list with no visible content — just an empty text area under your profile picture and name.
The Hangul Filler (U+3164) is an equally effective alternative. Both characters work on YouTube's web interface, Android app, and iOS app without being filtered.
