I will answer this honestly.
1) Lets start with a simple example, a football match, which is offered by every bookmaker you can imagine. There is breaking news, that team A will miss a lot of their players due to a flu. Odds are dropping like crazy in all bookmakers, but there is one bookmaker that is slow and has bad software. While all bookmakers only offer 1.40-ish for team B anymore, that bookmaker still has the initial 2.00 for them. Is it ok to bet on this 2.00 ? What if a bookmaker is constantly slow with adjusting odds and you could regularly do it ? Not for 2.00 -> 1.40, but maybe 2.00 -> 1.80.
I don't really depend on one bookmaker so I usually check others so I have no problem with this one.
2) By accident you discover that a bookmaker allows to parlay 1X2 and Asian Handicap market, which is of course a software issue. So you could parlay home win with AHC -0.5 for all kind of matches, which will give you good value odds. Is it ok to parlay these two dependant bets ?
I discovered it, so I will be using it. This is an exploit and not a scam.
3) This is the quote from user
LAngel from that thread above (can't quote properly, because thread is locked)
there was a cheat where if you activate bonus bet, and spin until you get the 5-hit fish bonus, and immediately restart the game before stopping the symbol selector whee, your session will continue as if you had the bonus bet on (extra bonus chance) but not have to pay double for spins anymore that entire session.
Is it ok to take advantage of this software issue in general ? For $20 ? For $500k ? (Leave aside the fact, that LAngel played with "cheated" money).
I will definitely take advantage of it, again, this is an exploit, it is a cheat. But, I can tell you, I will never be able to sleep for a while that is why I can just say that I will take advantage of it but, to be honest, I won't. Did I know this beforehand or I accidentally found it? Either way, I might take 2 bets or 2 before reporting this.
4) Lets say I have a trading bot (in betting or crypto exchange) and this bot goes wild due to misprogramming and I lose loads of money. Are all these users filling my orders scammers, when it's obvious that these prices are wrong ?
I think I will be frustrated but I agree with @kire - cryptzino
There is a fine line between a scam and an exploit explained by @Lakai01. And there are two types of people behind the exploit. The ones that would be taking advantage of it and the ones that would be reporting it. Though I can't exploit anything and I don't do scams since I am not that kind of guy.
