Assuming you would like tips on how to unblock a person:
There are a few ways that you can go about unblocking someone. If you have their contact information, you can try reaching out to them directly and asking them to unblock you. This method is most likely to work if you have a good relationship with the person or if there is some reason why they would want to unblock you (e.g., they need to communicate with you for work).
If reaching out directly doesn't work or isn't an option, there are also some technical workaround methods that might be effective. One way is to create a new account and then reach out to the person from that account. Another way is to use a different IP address or device when trying to access the person's profile or content. Finally, if all else fails, you could try contacting the social media platform directly and asking them to help you unblock the person in question.
