I recommend that you think hard and properly access your threat profile. You are likely going to have to pay with either your wallet (eg: some sort of company incorporation, lawyer fees, forwarding services, and other privacy protection services), your time (eg: using “inconvenient” services, managing separate accounts, etc.), or both. It can be draining (in more than one way) and take away some of the joy that you’re intending this to bring you if you do too much to protect yourself. On the other hand, if you do too little then you can overexpose yourself leading to pricey or dangerous situations.
At a minimum, I would recommend incorpating and making sure your name is not publicly tied to the company in any way. You will likely need a person/company/lawyer to be publicly listed as an agent of some sort for the company. You should be able to have someone do this for you for a small-medium sized fee. Once you have that, do everything in the company’s name and ideally with separate phone numbers, email addresses, online accounts, bank accounts, and physical addresses as anything tied directly to you.
Some of that is to protect yourself financially and legally, but there are some obvious privacy benefits as well. Anything beyond that should be dictated by your threat profile.
As always though, follow best practices when it comes to security! Use strong passwords and use multi-factor authentication when possible (or ideally, use passkeys). Don’t reuse passwords (and ideally, don’t reuse email addresses for multiple accounts). Avoid clicking links in messages when possible. Don’t open suspicious documents (especially if they are unexpected). Verify the authenticity of any new person/business you interact with (especially if they contact you first). Be vigilant of all forms of phishing attacks.
Another piece of advice (that you didn’t ask for, sorry!) - if the process of making art is the thing that brings you joy and the materials are not too expenses, then just focus on making the art without selling it (at least for a while). At worst, you will realize that maybe this isn’t as enjoyable as you thought it would be with the added benefit of not needing to deal with all the troubles of working through all the legal/financial/privacy protections. At best, if you decide to get serious about selling it then you’ll have a larger product inventory and better understanding of what you like making most. It may also help you understand what you should price everything at (assuming you’ve made some of the items in larger quantities).
I understand that there is a public benefit to this technology/data, but there are definitely concerns (including privacy concerns) even if the data is not currently widely available at a per household, per toilet, or per individual level. For example, insurance companies may not insure people who live in specific neighborhoods and it could lead to increased levels of surveillance through other means. There is also usually limited (or no) methods of opting out leaving a person’s consent to be questioned, especially visitors. Speaking of visitors, it could also enable location tracking/history of a person.
This really is just scratching the surface here, as is this technology. As the technology progresses, this can (and likely will) evolve into more sophisticated, granular, and wide ranged levels of tracking. Granted much of this is speculative, but the same thing has happened with computers, cell phones, TVs, cars, cameras, ancestry/DNA services, and many other services. As a result, its important to think of both current and future implications when considering the benefit and abilities of these technologies/data.
