Sorry to hear that, apart from contacting them directly I'm not sure what else can be done. I assume you've tried the message form in the FAQ? Also just a slight thing, you say you've emailed support@freebitcoin.in , the website is freebitco.in, so did your emails get bounced back or just not answered?

Freebitco.in is primarily a gambling site, and the site hasn't changed much, if at all, in many years; I highly doubt they have a large support team so any replies will probably take a bit of time.

For me, I see Freebitco.in as a free lottery. I've never bought fun tokens; just collected the free satoshis, exchanged RP for extra satoshis, and then withdrew those satoshis when I hit the minimum payout. You need an old style withdrawal address starting with 1 ... The site works and keeps gamblers gambling, they use lots of little tricks to make you feel really good about gambling; but the odds are always in the sites favour (on the multiply game, it shows you the odds you are getting; a 50/50 chance, wager 1 sat win 1 sat, you only have a 47.5% chance; the house always wins) - so why would they ever change the code if they didn't have to, or keep a support team around to dive into code that's been running for years?

Not your keys, not your coins, applies here. You and I have no control, and any resolution is going to come from getting in touch with them. I'd say be patient and wait for a reply, keep the screenshots safe, wait a week get in touch with them, be patient and wait...

I wish you the best of luck in getting this resolved.

You may be referring to a story a few weeks back where a Councillor suggested making trading in cryptocurrencies to be considered gambling, suggested in order to protect people from buying into things they know nothing about and losing all their savings on a dud project.

This will never pass anywhere close to government in the UK, not because it is inaccurate and not helpful, but because gambling profits in the UK are "untaxed" ....

So the first wallet balances to get recycled will be the genesis block and Satoshis'/early miners. At that point in time the block reward will have already reduced to zero, how do you propose to reset the block reward? You'll have a completely irregular supply of coins for the reward, you'll get a million or two BTC, and then after that you're not going to get big lumps and you might be able to track the possibility of any wallet reaching old age at a specific time, you can't be sure the owner won't move them and now you don't have new coins to hand out in block rewards. What kind of model is that for miners? By this point it is hoped that the transaction fees will be high enough to cover the cost of the miners, but you're going to release a bunch of "recycled" btc back out to them, do you know how that will effect the mining/transaction/user economy of the future? I don't.
I understand where the idea is coming from, but there are a myriad of factors you need to address to make this idea realistic or beneficial.

I think this might be what you have seen::

"The HTTP 402 Payment Required is a nonstandard response status code that is reserved for future use. This status code was created to enable digital cash or (micro) payment systems and would indicate that the requested content is not available until the client makes a payment."

https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/402

Can't find where the original source is but it might be from the W3C when HTTP protocols were getting standardised.

This is about how we trust the "book-keepers" and admins of transactions, how you have trust in a decentralised system. PoW forces the book-keepers to expend energy in a digital lottery where they try to guess the right number, competing against all the other book-keepers who are guessing as well; if a book-keeper tries to censor transactions, but fails to guess the right number for the block, their energy is wasted, and the transaction can get through any of the other book-keepers who aren't censoring anyone and happen to guess the right number.
That random nature of the contest, and being forced to expend actual "work" that costs something to do, is how you get trust decentralised.
