Dealing with poppy seeds, one has to account that not all seeds are created equal...err, washed equal. This person was lucky (or unlucky) and got good seeds that had not been washed, which is not to say they can't be found, but it varies from the source. I would also go so far, that you won't find this in every batch, even if they have not been washed, as you are dealing with a bi-product of the plant, how they were handled, how they were prepared for end consumption, and even the particular crop they came from. I fully support the use and abuse of poppy seeds, I just would not count on killing myself with every preparation based on this one outcome.
Getting involved with a group always feels like a bad idea when you are involved with illegal activities. Something you may also consider is that if they, or you as a group get caught, it likely will bring about your extracurricular activities. It is possible that it won't, but certainly something to consider and prepare for in the event you do choose to join this group. Even if you avoid getting caught, it only takes for someone to squeal while under pressure. Know well with who you choose to participate in illegal activities with.
How long have you been in contact with this group? How did they find you? What in particular was it that drew them to you or who suggested you to them? Did you do, or brag about a particular act(s) that piqued their curiosity? You may be dealing with a set up, similar to how law enforcement agencies will set up a sting. I have no doubt, that if you truly have gained some popularity with your computer science skills and your association with shady areas of the internet and subjects you study, that it would be possible that you are dealing with a trap being set. Notice I said "Possible", but even if this is not the scenario, it would be wise to learn more about this group before you get into something over your head. Why do they need you? What exactly do they expect you to bring to the table that they, themselves, cannot do? Is it possible to execute these crimes solo? What level of benefit is there to being a collective in this pursuit, and does the math add up for it to be practical?
I'd like you to answer, for the sake of my curiosity, some of the questions that would cause you no trouble in disclosing, but I asked these questions mainly to be rhetorical. Examine all the answers you have for the questions here to help you decide what course you should take. How we socialize with individuals will sometimes cloud their true agenda, also leading us to dismiss important questions such as these.
Being that you have asked this group of degenerates for advice in the navigation of this matter, and considering that you are a person with high intellect and social skills that surpass most of the user base here, it is my assumption that you have already made your mind up, and this was simply posted to stroke your e-cock, and possibly to talk yourself into consorting with these individuals. I imagine that you had a gut reflex when this was brought about, but greed and desire to flex your skills is what has your intuition hung up here. I believe it would be wise to go with your intuition on this one, considering the risk involved.
