How to Post a Blank Comment on Any Post – Easy Guide for Facebook, Instagram & More
Learn how to post a blank comment on any post on Facebook, Instagram, TikTok, and other social media. Step-by-step methods using invisible characters that really work in 2025.
Posting a blank comment on social media platforms like Facebook, Instagram, TikTok, YouTube, and WhatsApp is a fun trick that often grabs attention, creates curiosity, and adds a unique touch to your interactions. Whether you want to prank your friends or stand out in a sea of comments, this trick works across most platforms using invisible Unicode characters.
This SEO-optimised guide explains how to make a blank comment on any post using simple steps — no apps required.
✅ What Is a Blank Comment?
A blank comment is a comment that appears empty — with no text or emojis — but is still posted successfully. Social media platforms usually don’t allow completely empty comments, so we use special invisible characters like Unicode U+3164 (Hangul Filler) or Zero Width Space (ZWSP) to bypass this restriction.
📱 How to Post a Blank Comment on Facebook
Method 1: Using a Blank Unicode Character
- Copy this invisible character:
⠀ ← (This is a blank space – U+2800 Braille Blank or U+3164 Hangul Filler). - Go to the Facebook post.
- Paste the blank character into the comment section.
- Tap Post.
💡 Note: Do not press spacebar or enter multiple spaces — Facebook filters that out. Only paste the copied character.
📸 How to Post a Blank Comment on Instagram
- Copy this invisible character:
ㅤ ← (U+3164 Hangul Filler) - Go to the Instagram post or reel you want to comment on.
- Paste the character into the comment field.
- Tap the Send/Comment button.
🚨 Instagram’s filters may change over time. If one character stops working, try an alternative like Zero Width Space (U+200B).
🎵 How to Post a Blank Comment on TikTok
- Copy the blank character from here:
⠀ ← (Braille Blank or ZWSP) - Go to the comment section of a TikTok video.
- Paste and post.
🎉 Works great to gain attention or go viral — blank comments often get likes and replies due to their mysterious look.
🗨 How to Send Blank Messages on WhatsApp
- Copy this character:
⠀ - Open a chat in WhatsApp.
- Paste the blank character and tap Send.
This trick also works in WhatsApp status, group chats, and even broadcast messages.
🧼 Bonus: Other Working Invisible Characters
If one doesn’t work, try any of these:
- U+2800 (Braille Pattern Blank): ⠀
- U+3164 (Hangul Filler): ㅤ
- U+200B (Zero Width Space):
- U+2063 (Invisible Separator)
- U+00A0 (Non-breaking Space)
💡 Tips to Remember
- Do not use regular spacebar.
- Always copy the exact character (not extra spaces).
- These tricks work for both Android and iOS.
- Some platforms may update and block certain characters, so keep trying different ones.
🔐 Why This Works?
Social media platforms detect regular spaces and empty input fields to prevent blank submissions. However, Unicode has special characters that are technically not empty, even though they appear invisible to users. These are non-rendering or zero-width characters.
⚠️ Disclaimer
Using blank comments isn’t harmful, but excessive use may lead to temporary restrictions on some platforms. Always use responsibly and avoid spamming.
📌 Final Words
Posting a blank comment on any social media post is a cool and harmless trick that you can use to surprise friends, go viral, or stand out in a comment thread. Just copy the invisible character, paste, and post — it’s that easy!
