Whether you’re dealing with harassment, bot spam, or just plain unpleasant interactions from other X users, blocking accounts can put a stop to it. But if you block someone on X, do they know you blocked them?
How to Block Someone Who Blocked You on Twitter x (Easy 2024)
You can quickly block any user on X. Go to their profile (on the web or in the official mobile app), select the three vertical dots next to the Follow/Following button, then select Block @username.
Blocking a user prevents them from following you from that account. If they try to follow you, X will show a message that says, “You have been blocked from following this account at the request of the user.”
X will not send you a notification if someone blocks you. The only way to see that you have been blocked is to visit the other user's profile and see the X block message.
