Interesting, you write about bots winning at nl100 and this thread gets so little attention. If those bots can play profitable on nl100 then they likely play all stakes below nl100 with multiple accounts. If they do collusion, and have solid strategy they are so tough to play against and make those stakes very hard to beat for other players. They likely play also on all other casinos unless they still didnt have time to create that many accounts and configure them but they surely will. If there are micro stake bots that struggle to play BE it is not a huge issue because they generate traffic and ate exploitable so humans have still chance to win money. The big problem is existance of solid bot which uses multiple accounts on multiple casinos and is the only winner at most stakes. Then the whole profit is shared between casinos and bot owner.
If you are sure that those accounts are really bots because have super similar stats, why dont you create a report where you display names of those players and like 20 preflop and 20 postflop stats. That would be a proof so that everyone can see it. The way you reported the problem looks to unaware people as conspiracy theory. If you report them by providing report which shows that they have identical stats, casino might block them because they would be afraid that it goes public if they don't. Then bot owners would loose like 10-20k euros on those accounts, and would soon create new accounts. Then you can again see using pokertracker or holdem manager which players have identical stats on NL50, NL100 and report them again. They will have hard time changing strategy for each bot so that bots produce different statistics. You will slow them down a lot by doing this.
Just think what would happen if you start reporting bots on all networks except stars? Traffic would be so low so it wouldnt be profitable for most casinos to pay half million $ for gambling licence. Ipoker traffic is rapidly decreasing even though it is full of bots. Most of networks are full of bots. Stars is the safest to play, only bots that are very profitable can invest enough in stealth or even pay humans to click what bot suggests. Just visit http://www.poker-bot.org/main/,http://www.bonusbots.com/, https://www.pokerbot.com/, http://www.abzpokerbot.com/en/. there are 4 commercial big websites that sell bot profiles. Those profiles are bad cheap bots can make very low profit but still it is better to play vs fish than vs breakeven bots.
The point is, you can complain to casinos but casinos dont do anything about bots. They know that it costs a lot of money to have good bot detection and that they cant detect bots that play with humans clicking and watching what bot advices so they rather let bots play and try to keep it as secret.
You can go to www.maxinmontreal.com which is big poker bot community sharing code and knowledge, most of guys have phd or at least master and cooperate. So what ate the chances of ipoker, party poker and similar networks to be better than those guys in detection of bots, when casino can pay several guys to work on it, and in bot community there are more than 1000 guys. Casinos cant even solve software bugs, connection issues and similar stuff, so how can anyone expect them to do very advanced things like bot detection which you cant learn at school.
The newest trend in bot community is gto solvers. They put on server all gto solutions for all scenarious (solved by gto solver and similar). Then load single solution from server to local machine while playing, and thus play identical strategy as gto solver suggests. It requires powerfull pc a lot investment, and few of such bot owners already reported to be able to win at highest possible stakes.
This will be the end of online poker for human professionals which will happen likely in 1-2 years until bot owners manage to create enough accounts, PCs etc, and all we will all have to play live games in casino.
You can read all this info on maxinmontreal and poker-ai.org. all infos there are public, they dont hide anything, discuss about poker and bots like we are doing it here.
