All I mean to say is that as long as I am getting seeds that look about right for the species and they are germinating, at least for now, it is good enough for me. I also admitted that once I have more plants, I may not appreciate getting common seeds for something exotic I buy. "Authentic" seeds are pointless if they don't germinate, and outside places with a good density of growers, it is hard to get any seeds at all. For Nepenthes seeds, I don't know a single other place I can get seeds and reasonably expect them to germinate and I've been a fairly prolific buyer over the last several years. So gambling over a possibly wrong ID isn't that big a deterrent. The thing with a gamble is also that the seeds may be right or wrong ID, but still be interesting plants.
Sure, if you have a good collection of nepenthes and would prefer to not waste time and space on common species AND you have access to reliable seed, your view makes a lot of sense. Heck, if I had access to buy/trade the kind of hybrid seeds I hear talked about here, I wouldn't buy on ebay either. So far I've asked plenty of people on different forums, and no one has been willing to ship seeds to India.
About rewarding an intentionally fraudulent seller... I don't know that they are intentionally fraudulent sellers - if we are talking of the ones that sell actual nepenthes seed, as opposed to the Chinese fraudsters. I know that there is a possibility of mislabeling. I don't know enough to be confident it is deliberate!
And as for mislabeling or intentional fraud, I've purchased an N. rajah x veitchii and got what is most likely an N. truncata/robcantleyi x veitchii from an allegedly reputed nursery. I paid thrice the cost, got plant with ID I can't be certain of, AND no replies to emails. And I am fairly certain this can't be accidental, because the same order had a robcantleyi x veitchii as well, so essentially, I got two of them, just different sizes, so the pitchers of one being juvenile, they looked different.
The seeds are way cheaper fraud.
