That should not happen, we never block anyone from anything else on the site. Please PM me your user ID and we'll take a look.
But is SM really that "easy" to be exploited by bots?
It is a question of the level of difficulty to exploit. That is what determines the cost to them. reCaptcha is 2x to 3x more expensive to solve than any other.
Can somebody advise how do you get back the base reward properly?
Deposit $50
Also:
The algorithm for reducing rewards takes a combination of the balance, wager, lottery and jackpot spending to calculate the reward. Jackpot spending has a higher weight (4x) and the lottery has the highest weight (20x).
If you do not want to gamble you can keep a balance above $50 to not have reduced rewards.
Most users will not need to keep the full balance though because their gambling history is also added up to calculate.
New accounts have full rewards for the first 100 rolls to help them build up a history and then the algorithm is applied to them. So opening a new account might seem like it helps but it won't.
Additionally, the balance needed to have no captcha is $100.
