That doesn't make sense. Just open a bunch of accounts of 90 btc and who would know better. Even idiotic governments would know this.
It's not a question of what can be done, it's a question of responsibility of the web site owner. If the website owner is responsible to ask for a name, and he gets dozens of names generated from a random number generator, is it his responsibility to go through names and see if they realistic names?
In the USA there is an upper limit for private cash transactions. It is $10,000 . Now there are plenty of illegal cash transactions in amounts below $10K, but the government requires you to report to the IRS a cash transaction of $10K or more. There is no presumption of illegal activity. You might pay for an old sports car in cash for some amount over $10K. There is nothing illegal about buying the sports car, but it is illegal to not report the transaction to the IRS.
I am not sure of the law in Canada. Now $10K < 17 BTC. So if dooglus is required to register with the Canadian government every investor deposit of 17 BTC or more, than he probably can't function.
If a more reasonable sum is determined, than he may have a workable business. As of the last report, these are the top investors in doge-coin (expressed in BTC)
693.71

233.82

213.95

If he can meet government regulations by restricting investments to the dogecoin equivalent of under 100 BTC, and is only forced to produce a list of investment or withdrawals on demand then he might have a working business model that could operate under the radar.
While some people will be reluctant to turn bitcoins in doge-coins, there may be enough to restore business. Doge-dice made 2200 BTC equivalent in profit, which is a little more than 1/8 of the profit of JD. I don't know how long Doge-dice has been operational.
In general, the government will have to win cases to establish precedents. They are much less likely to go after a dogecoin operation for one of the first test cases. Who wants that story in the news.
