I talked to Jack at Win A Day, here's the answer I got. It's looking promissing and along the same lines that they have mentioned before. I figured a VIP manager might be one of the better ones to talk to.
Hi xxxx,
Thanks for your feedback at the forum and for your note.
In general, all automatic bonuses are mandatory unless requested otherwise, where admittedly one might need to be quite persuasive to get the bonus removed, which might also lead to account termination in some rare cases should it be red-flagged during the scrutiny the account gets under.
On the other hand, all bonuses at Winaday will soon start to be handled via bonus codes, which means it will be solely upon you if you are okay with the bonus terms hence grabbing the bonus, or letting it go instead if you find the bonus terms too challenging. Subsequently, a similar change is about to be introduced at Slotland, although there is no exact date yet.
I'll be happy to check the other forum you're talking about, if you kindly let me know the address or send me an invite. Much appreciated!
Cheers Jack
