I'm not going to comment on how to do sourcing or anything and i'm arguing against it however
Learn more about cybersecurity, even if you don't know much about computers or privacy. Specifically for the community surrounding drug forums it would be more important to use TOR than something like mozilla firefox or Brave and opening a private Brave with TOR window (it's important to actually use the TOR browser instead!).
Use a VPN. Brave doesn't have a built in VPN on MAC and Windows and instead uses a feature called TOR which is an encrypted network that hides your IP. On Iphone and Android Brave does have a VPN. You will need to research which of these are better and maybe someone with more experience can comment on that but I'm not majorly knowledgeable with internet privacy and cybersecurity and I just have some basic understanding of how it's important to everyone to protect their own privacy from their employer, government, and databrokers.
Don't click on embedded video's like embedded youtube video's because that can track your activity, even in some instances where you are still taking measures to protect yourself. It gives Google that information and that can be sold to third parties like a data broker such as Lexis Nexis. (I actually need to edit a few posts and remove links to youtube and replace them with something like titles)
Go to the Electronic Frontier Foundation's website at EFF.org and read all over the website. Check out the whole website and over a few weekends you can start to understand the consequences of data and privacy. Maybe if you want volunteer to do some good if that's your choice. I learned about EFF from DemocracyNow around the repeal of Roe vs Wade and it became more pertinent for medical providers to protect their security due to legal ramifications. Regardless EFF is awesome. They even have a lot of tools, i'm posting a link but feel free to search on your browser instead. I'm not sure if that actually embeds a link? again, I know some basic measures but i'm not an expert in the field.

HTTPS is also great.
That's just cybersecurity but I think you should consider growing plants rather than ordering raw material. Raw material is very unsustainable. Ordering root bark for example contributes to deforestation. Let's say that you order some Caapi vine or something, whatever. Well, you have no clue if that was sourced sustainably and there are no regulations or checks and balances for these kinds of things. How do you know that you've bought a product that caused the destruction of an endangered habitat? There's a bunch of greenwashing involved in a lot of ethnobotanical online shops too which is a spit to the face as far as i'm concerned I dislike being blatantly lied to. It's improbable to verify without looking at the carbon in the wood. (i'm not sure about the specific analytical methods but i'm going to share the title of a documentary from DW Documentary called "From rainforest to Charcoal" and just look it up)
There's times when you can't do much of anything or at least need more of an in depth knowledge of security to protect yourself. Just look into the Pegasus spyware made by the Isrealis government which can just exploit a little bug yet to be fixed in an update and install into your device without having to click on a phishing link. Scary. It may honestly be best to achieve enlightenment and non ordinary states without breaking laws in regressive countries.
Also, for most people living in the U.S. or China or otherwise leaving their country may only be accessible to privileged few. I would recommend weighing whether or not volunteering or activism is something that you can do and trying to make things better overall for everyone. If you find that the risks of that outweigh wanting to make a positive social impact then simply don't take on those risks. Don't use entheogens if it honestly puts you at risk. Protect yourself above all else
I'd like to note about cryptocurrency too. I'm no expert but here are the reasons why I don't use it or care for it: it requires a massive amount of electricity and power to mine cryptocurrency resulting in emitting a massive amount of methane. Hypothetically if we were already transitioned toward a completely renewable energy grid such as Wind, Solar, Nuclear Fusion (not fission! before anyone yells at me!) or etc. I would be with the whole bitcoin thing. The other reason is that it's rife with theft in some instances. I prefer to us regular banking with a credit union or with Atmos Financial (they only operate in the U.S. so if you live in another country you'll need to look into sustainable banking where you can). I also like to use both credit unions and atmos financial because it's nice to spread your portfolio around a little to access the services you may need
Finally keep things separate. Don't do a bunch of different searching while also reading on DMT Nexus or doing activism. Sometimes you can search in using a tab with DMTNexus open while just looking at a youtube video and youtube see's that as unusual traffic and blocks you from their site (and maybe flags you? I'm not sure, someone with more knowledge please comment)
That's all I have to say, please stay safe.
