"Online drug marketplaces are run by MI6" (assuming that's what you meant by "SIS") isn't an opinion, it's a statement of belief. And a pretty unlikely one, I have to say.
As for Albanian gangsters, the last thing I bought came from a man in Germany with a German name. *shrug*

Pretty unlikely, eh?
Silk Road and Hansa were infiltrated by police/SIS. A lot of these operations are. Same kind of deal whereby the music and film copyright protection companies seed torrents to catch users and ringleaders. You'd be mad to think GCHQ aren't watching you when you turn on your VPN and make crypto transactions via known criminal networks. DARPA has publicly stated they have software designed to monitor the dark web.

There was a British marketplace infiltrated in the last few years, I recall reading about it on BBC News but can't seem to find the article right now....

Right, but what are they gonna do - arrest literally millions of people for buying trivial quantities of drugs?
If anything happens it'll be the vendors they go after, and even then, probably only the minority who are shifting really significant amounts.

Infiltrating the network is the primary goal
(and by your participation, you became part of that network) but of course, they want the big fish.

That said, examples are made, and if they can't get you for something else, this would do.
