I tallied all the casino threads in Scam Accusations that were either posted or bumped in the last year (17 pages -- it should be noted that many of these complaints were resolved, miscommunications, erroneous or duplications), and here is a list of the top 10 casinos by total # of threads, along with their domain rating according to ahrefs (a rough indicator of the popularity of a website based on its number of backlinks):

BC.GAME: 44 - 79
Rollbit: 37 - 62
Stake: 28 - 80
Shuffle: 19 - 63
Sportsbet.io: 17 - 76
Freebitco.in: 12 - 80
TrustDice: 9 - 68
Fortunejack: 8 - 70
Chips.gg: 7 - 40
DuelBits: 7 - 66

So dividing the complaints by domain rating gives you an idea of how frequent complaints are relative to the site's number of backlinks:

BC.GAME: 0.557
Rollbit: 0.597
Stake: 0.35
Shuffle: 0.302
Sportsbet.io: 0.224
Freebitco.in: 0.15
TrustDice: 0.132
Fortunejack: 0.114
Chips.gg: 0.175
DuelBits: 0.106

So this does put BC.GAME on the high side.

Another way to measure would be by complaints/traffic (in thousands of hits per month, also from ahrefs):

BC.GAME: 44/649.7 = 0.068
Rollbit: 37/22 = 1.68
Stake: 28/1700 = 0.016
Shuffle: 19/15.3 = 1.24
Sportsbet.io: 17/560.2 = 0.03
Freebitco.in: 12/431.1 = 0.028
TrustDice: 9/17.3 = 0.52
Fortunejack: 8/8.4 = 0.952
Chips.gg: 7/0.666 = 10.5
DuelBits: 7/12.7 = 0.551

Here the results are much more varied, but BC.GAME is much lower than average.

The point being, if a site get a lot more traffic, its bound to have more complaints.
