If I had to guess, I'd think that OP put in a lot of entries into the September Sweepstakes for this item (found here:
https://1.shortstack.com/8DzfMr), but from what I can tell those sweepstakes are over.
If he has large quantities of codes my guess is that more than likely they figured out a way to hack the code progression like with the Google Home deal. Note that from the link you posted NY and FL residents are excluded and I think the OP mentioned only 1 per ADDRESS. They are being sold on eBay from $49 new and up.
Huh, I thought the Google home deal was just many entries. One guy was selling echo dot codes that were from a siriusxm event, and there's no way he cracked those because they were all randomized and lengthy. The main reason I'm guessing this is a bunch of entries is because the entry form for the promotion has 0 verification that you are not a robot. No Captcha, no cookies preventing you from entering multiple times, etc. 1 per address makes sense because I'd imagine you're supposed to be limited to 1 per person/email. Maybe I'm being too optimistic. Hopefully I didn't buy cracked codes -- once I saw that sweepstakes submission page I just assumed it was a set of spammed entries.
That's why I said I was "guessing." What are the odds (unless it was some kind of system error) of them giving away free cameras to everyone who entered a sweepstakes? Maybe not a "progression", but an exploit. The Google Home codes were def some sort of exploit because not only were there thousands of them but someone was selling a code generator. Like everything else here they certainly aren't obtained by "normal" means. It just logically makes zero sense.
I don't think it's a matter of the system malfunctioning/erroring though. In my eyes, it's a question of:
1) how many people actually entered this giveaway (I personally don't see too many adverts about it anywhere online, so I don't know how too many people could have found it. I guess it could have been through physical advertisement or something)
2) would OP actually have been able to create enough and parse through emails/aliases/whatever to keep up with all of these entries? I'm more concerned about this step. I found through a simple online search that Cannon was giving away
2500 of these codes. Last I remember, OP had around 300 codes in stock. This means the sum of OP's entries make up around
12% of total entries. If the sweepstakes weren't actually well advertised, I don't find this too crazy of a number; botting is quick and requires little to no hand holding.
We'll see what OP says.
I will not expose the way I actually botted it. I would be giving away a method that took me a lot of time to make.
Given the proof and the link to the giveaway posted here I think it should be obvious to anyone that those codes come from this giveaway so I am not going to provide any further proof on that.
