Responsible gaming? What are you talking about?? You really think casino make money from responsible gamblers? 99.9% of all gambling related business run their business thru people who gamble too much
There is some truth in that. While 99.9% of deposits are not off people who have gambled too much... Quite a few are.
Look at it this way. Some slots these days are encouraging longer play times. Take the Dark Knight Rises as an example. You accumulate free spins through the "random" fight's and play them by getting scatters. Lets say someone gets 30 free spins with a x3 multiplier accumulated but they bust out after spending their set gambling budget for that day. I really doubt there will be many people who say "oh well, my budget's gone and i'm quitting at that. Not going to play again until next payday in 30 days time". I'm pretty sure that most people would have that extra deposit to see if they hit scatters and can play the spins. While the bonus round could still be shit, it's very tempting to have that extra deposit just in case. Quite a few other slots are like that too.
As for the bank allowing him to deposit 22k in 5 hours.... That's normal. When it comes to taking cash out there are limits (mine is £300 per day). I guess this is because it's quite easy for someone to use someone else's card to take out money (All a fraudster would need is the card and the pin). Whereas to take bigger amounts out in cash you need to enter the bank and have ID documents to prove you are the account holder.
Online it's more secure so is likely that the person using the card is the account holder (Plenty of verification takes place. Often if the card name/address doesn't match the name/address given to the payment processor, it will decline. Plus theres things like verified visa and so on). Plus people do tend to make big purchases on their cards. Nobody would walk into a shop with £10,000 in notes to buy something.... They will use their card. So if a bank sees big money going out, it doesn't necessarily mean it will be flagged.
Most banks do flag accounts though is if x amount of transactions are made in quick succession. They will block the card and require telephone verification to confirm that it was you who made the transaction. I have been caught out on this a few times where I was paid and had phone, internet and other bills to pay. I went through each site, paid each bill with just a few minutes gap between payments. Next thing I know my card is blocked and I had an automated call to verify that I made the transactions.
In the OP's case since he was depositing, playing for a while and then making another deposit, there probably was a long enough gap between deposits to prevent a flag going on his account.
As for the "limit" the player claims to have.... Not a chance in hell do I believe that.
I funnily enough do have a limit on my Betsson account (sister website) and to be fair, their systems work very well.
Just for argument's sake I just logged in now, put that I wanted to deposit $300 on card. Before it even got to the payment confirmation page, "Your deposit amount exceeds the maximum allowed." popped up.
I then did the same thing with skrill deposit.... Same message popped up.
The cooling off period works well there too. When you try to increase or cancel a limit it still takes 7 days before the limit is increased/cancelled. I have done this too on previous occasions (over the past 5 months) and all worked as it should.
Regarding Betsafe... while I closed my account a while back (So I can't confirm it works this very second), I did have limits on that account too and just like I mention above with the sister website betsson, it always worked as it should. (Even though Betsafe were bastards to me at the time as I did not have valid ID back then. I wont ever forget that rude email off someone called Karl or something like that telling me "Get a passport to use as ID and we will pay you")
If I had to put money on it, I would say the OP cancelled the limit some time ago and the 7 day cooling off period has passed.
