I am working with Xvideos for more than 5 years and had hundreds of accounts.
Your IP, subnet, or even country affected you are ghosted. You can try to make another account on mobile 4G, try changing 4G providers, etc. Or use residential (only) proxies, but these already can be spammed.
There are 2 initial steps - you need very clean and fresh IP for account creation and uploading first video. If you are not ghosted after that - you can use less good IPs for next uploads, but it is important these IPs should not be blacklisted on Xvideos.
If you are going to go with your 100% unique content - create a channel.

But do not use same watermarks, intros and outros on your videos - they will delete your account without warning.
Also, you can try contact them for channel by email from
[email protected] etc.
