Final answer:
When you see the message that you can't send a message because the user doesn't allow requests from everyone, it's due to their privacy settings. You can try sending a friend or follow request to fix this issue. Always respect other users' privacy settings and preferences.
Step-by-step explanation:
If you're receiving the message “This account can't receive your message because they don't allow new message requests from everyone,” it means that the user's privacy settings prevent them from receiving messages from people they aren't connected with or don't follow. To fix the issue where they don't allow new message requests, you can try sending a friend request or a follow request, depending on the platform you're using. If they accept the request, you will then be able to send messages to them. Alternatively, you can look for an option to request permission to message, which some platforms may offer.
It is important to respect other users' privacy settings and decisions. If after sending a friend or follow request your message is still not deliverable, it's advisable to refrain from trying to bypass their privacy preferences. If you need to contact the individual for an important matter, consider using alternative methods they have made publicly available.
