Yes, there is that nuance, but:
1. It is displayed to you and you alone
2. On receiving the data of your IP, at least here they warn you about it, unlike other resources 
3. find in this and a good component - it can be used to check that your account is not used by someone else, respectively from another IP, because all your posts are labeled for you IP from which the post is made 
Thank you, I have found it. With the IP address we only think it is a privacy problem because the authorities can find out every IP or ask if they are stored, especially in the mixer area.
Now we will check whether the information is stored inside the service or not. Now I’m using a VPN, with an address in a completely different country and even a different continent

If my previous post and this one have 2 different IPs, that means they are stored and tied to each individual post... Now I’ll publish it and write down which ones IPs are displayed for me...
UPD.
The previous post shows IP 46.1**.*.*
The current post does not show any IP address...
In total, I can assume that there is a certain address that can be stored as a “base” address for the user. And if he comes from another IP, then it is not displayed, informing that this is a “different IP”.
In a word - it is better to seek advice from the owners of the resource
