Seems like way too much over thinking for something you say you won't even hardly use. Like going to different grocery stores so no one knows what one you're going to buy from next or something.

If you don't want to abandon an account after a single post then only thing as others have mentioned is self displicine in what you share. General topics like inquiries on games, tech, and movies are probably of no special interest.

But, stuff like I'm from Atlantis and I am of noble lineage of the lobster clan who is part of an alliance to overthrow the clan of Corrals is too much info to be giving. Basically don't share stuff you wouldn't be comfortable people knowing in real life.

If there is this much paranoia though I think just lurking is the way to go, and keeping only an account for asking questions that is worded as unassuming as possible. Maybe even have AI rephrase what you wanted to ask.

As an admin, accounts are quite cheap and we get thousands of them just through federation. They're just a row in a database of tens of thousands of rows.

I wouldn't worry about it, the only issue is if you make them random strings of numbers you may find it difficult to get past some spam fighting measures. But apart from that, I wouldn't worry about it. This post as a whole with the comments probably takes like 10 accounts worth of storage.

If you are a human posting, you're contributing to the community. It shouldn't matter if it's your only or have X accounts that you use/don't use. In general, ddos attacks are more timing related in combination with data quantity not just raw data, since a new user account doesn't take up much space and neither does their posts (this isn't 100% the case, but usually the case. Also haven't read lemmy's source code, just general discussion)

You can always donate your account to the privacy community and someone else will use it to post. Over time these accounts will have lits of different people sharing metadata and mixing the waters.

Im not saying to do this or not. Just that its an option. There used to be an add-on for this called bugmenot. The instance will likely have your IP for a while but you can always use a VPN/ TOR or a coffee shop if you feel you need to hide your IP.

I don't feel there is any harm in having several accounts spread out for whatever purposes. Compartmentalize it so that each user is distinct and keep the accounts. I think this is the best way to maintain privacy but also not create new accounts constantly. Pretty sure this is good enough to not expose yourself.

Just curious why you’d go to such lengths to maintain privacy.

I’m going to go out on a limb and say you’re probably of no interest to any authority. Unless you KNOW you’re doing something illegal.

To be clear I’m not saying that we all shouldn’t value privacy but, for example, could you not just keep an account for 6 months then delete?

Or are you worried that some 3 letter agencies will bust through your door within that time frame?

You could occasionally post or comment with innacurate personal details such as living in a different city or having a pet or interest you don't actually have. In addition to the other advice in these comments.
