You have to make your own decision on that issue and accept the impact it may have on your chances of publication.
My recommendation would depend on your field. If you are dealing with a cryptography journal you might be able to share your PGP information (or encrypted email address) and "anonymous researcher of topic XYZ"
For other Journals you may be forced to provide the name of an actual organization with a mailing address where you can actually receive mail. Whether or not a pseudonym is acceptable will depend on the Journal and whether your organization will vouch for you in some manner (perhaps least by accepting mail addressed to your pseudonym and confirming your affiliation with the organization without revealing your identity).
If you want specific advice, the name of the Journal may help (if someone here is knowledgeable about their policies). What you want to do may or may not be possible.
I will ignore any taking credit and ethical concerns since you have already read those discussions.
Of course I am assuming you have a good reason to do this, otherwise you are making things much harder on yourself than they need to be.
