I don't think anyone at Neteller can discuss such matters
as fraud with their customers, no matter how much a VIP that person is. That would be to admit they have a security problem and I doubt they will do that.
The fact that only UK are prevented from using Neteller speaks louder than words, so I say I rather believe the casinos in this.
They don't want to lose their customers. The easier it is for us to deposit the more money they'll get.
You are just speculating but are making it sounding like you know the truth. You're good at that
Actually, a betting syndicate is not fraud, nor is it illegal. It only becomes fraud if deception is involved. The terms I have seen exclude Neteller deposits from the bonuses, and don't mention specific countries. Country based exclusions are often regardless of deposit method. I have seen the UK excluded, but also the Nordic countries seem to have been a hotbed of fraud as many casinos have excluded countries like Sweden, Finland, etc from welcome bonuses, so this isn't just a "UK thing". It's closer to the truth to say it's a "world thing", but it can come in surges from differing countries as one exploit is found, gets plugged, and then another opens up.
However, is it right to demonise ALL Brits because of the actions of a determined few, or for that matter, demonise all Finns, all Swedes, etc. It's probably down to laziness, easier to insult an entire nation than to tackle the few players that are causing the problems.
When it comes to actual fraud though, the country it appears to come from may not be the country it actually comes from, that is the whole point of setting up a fraud, it has to be hard to track down. With the EU freedom of movement and labour, it is very easy for any EU national to move their activities to another EU country if their activity is sufficiently profitable for this to be worth while. Maybe it's not UK nationals that are giving the casinos a thorough working over, but other EU nationals taking advantage of the fact that they can easily move to the UK, even if only virtually via something like a VPN, and benefit from the until recent liberal attitude to online gambling here as opposed to restrictions in many other EU countries.
Unfortunately, Neteller and Skrill have cornered the market, there is no alternative that offers the same hassle free experience. Cards are unreliable because of banks' ultra sensitive "automated suspicious transaction blocking". Voucher based methods are a pain because it means going down the shops to find one that has a Paypoint terminal, and staff that actually know how to sell a Paysafe voucher, which is pretty rare as most staff are used to using them to pay energy bills, top up cards, phones, etc. PayPal is just as good as Neteller, but it's not widely accepted even at UK licensed casinos.
One of the biggest problems of all is that ONLY Neteller can properly serve a high roller, the other methods will severely limit maximum deposits. The vouchers are limited to £100/£150, and many bank cards will flag and probably block casino transactions over £100 as "suspicious". Casinos could end up losing a lot of turnover from it's best players if they are forced into using cards or vouchers. Other casinos of course can snap up these players by not restricting Neteller.
It seems to me that the browser based casinos are far more likely to have such anti Neteller terms than the download client casinos like 32Red.
