In a lot of sportsbooks the bonus terms are so convuluted that if you don't follow them completely they can then say the bonus rules weren't followed so some of your winnings (built off the bonus) are no longer valid.
If you opt to decline taking the bonus since you don't want to follow the convulted betting requirements to satisfy the bonus or the larger rollover requirement are you going to be considered a suspicious account and warrant closer monitoring from the sportsbook?
There is nothing suspicious about a bookmaker. Typically, they use a methodology not easily found in other sportsbooks. Football odds are published by average bookmakers across the globe and are updated continuously to reflect odds available in different books as of any given moment. There is no evidence whatsoever to suggest that these books are scoop operations' or otherwise engaging in anything but spot-on market research. You would know this if you were a bookie too. I didn't know how to make a betting site, and that's why I got the already made software from the bossaction website.
