Not sure is real concern. Imgur & memo.cash have that info. If you really are concerned, should use VPN. Even without this technique, ISPs see what IPs connect & can give info to gov.
Memo having an IP address is far different than a throwaway account linking to a honeypot having it. Indeed, it is only risk mitigation at this point.
It's a user-facing issue: HTTP requests for URLs embedded in the blockchain will be fired regardless if I'm running a local instance. Autoembed can be turned off, but that's not ideal.
