If I recall correctly, the 90 days was part of their terms and conditions to which the OP signed up to. Those 90 days allowed the game providers to check if cheating had taken place therefore that should not be held against the casino.
LT Casino stated they will allow the withdrawal on the basis of technicality as they have one confirmation cheating took place and one where there was nothing. Either way the OP is withdrawing and the casino have been true to their word thus far but without a shadow of doubt those that placed tags should keep them at least until the full amount has been withdrawn.
I think it is reasonable to keep the negative feedback and support on the flag as long as the user isn't getting his whole amount. Because, they were holding the funds of the user for more than 3 months without any reason. However, I respect the decision of “Slow death” and “Jawhead999”. Everyone has a different view. Hopefully other DT members aren't going to change their decisions anytime soon.
