Cant visit Indiegala, I get blocked

My account, and the accounts of several others- I think I was up to 23 other unique cases by the time I stopped my searching into other potential cases. For most of the reports I got, people indicated they had gotten auto-locked-out by glitches in IG's security (much like what's happening in this thread, but tied to an older system which had a much more forceful outcome). For others, the situation was the same as mine- we'd contacted support about a separate matter (in my case, the fact that their site overcharged for a bundle by a couple of dollars), and the next thing we knew, our accounts had been locked.
In each case I found, support refused to provide any response to e-mails, and eventually fully deleted the account in question.

As far as my own circumstance, I contacted IG dozens of times over maybe 8 months (for over half a year, in any case), via all of e-mail, Facebook, and Twitter- not only did they not respond to me once, but they immediately deleted my Facebook and Twitter messages each time I posted them. This was true for my initial "what's going on?" questions, as well as for my "Okay, whatever- can I just get my unclaimed keys, please?" ones.
I had purchased $35 of keys, maybe more, from IG up to that point, and most of the keys had been unclaimed at the time my account was locked. All in all, it ended up being a loss that was as expensive as it was inexplicable.

While I did find enough similarly affected individuals to validate that it's not a unique circumstance with IG, the overall scarcity of such reports seems to indicate it's a fairly rare occurrence by the numbers. So generally, it's probably not going to be much of a risk- then again, that's like playing a reverse lottery. If you "win", you risk losing quite a bit. [In that sense, it's much like using G2A and running the (purportedly) low risk of getting a non-functioning or revoked key. It may never happen to you, but it's still a risk to keep in mind when using the site.
With that in mind, I make sure to regularly warn people to back their IG keys up immediately after purchasing them- if there's nothing for you to lose from an account lock-out, then you clear out most of the risk of using IG (though they do have some infrequent issues of not replacing invalid keys, as well- but they also tend to compensate for their all-too-common happy hour purchasing bugs by giving an additional bundle (or bundles) over the one(s) they failed to give in the first place, so perhaps that's an issue which balances out in the long run).

Personally, I find them far too scummy to give my money to ever again; that said, if you haven't lost anything to them like I have (and thus lack the motivation to avoid them entirely) then you really should be able to cover your ass with just a bit of extra time spent on key management.
