Ok, I play small stakes on SwC, and have successfully reported colluders before (with my HH evidence). I like to think I am playing on a fair site, so I gave OP the benefit of the doubt and started to look through the HH's.
First, it seems clear they have been edited. The most obvious one is the hand starting at line 710, which is incomplete. OP is dealt KK otb, rest of the hand is missing, and his stack size is unchanged for the next hand, showing it was folded. Red flag 1.
Good find about the KK hand, this also makes me curious. Looking at the stack size next hand it is apparent that OP folded KK in the button and then the sb folded to the bb. Yeah, folding KK on the button makes no sense, unless it's misclick of course. There was also no time out or something since the next hand started fairly quickly.
Strange also that the rest of the action is missing, doesn't even say anything, no show down, no summary, no nothing, while it should look like this:
*** HOLE CARDS ***
Dealt to gd1990 [2h 7c]
gd1990: folds
Uncalled bet (200) returned to MichaelDE
*** SHOW DOWN ***
MichaelDE: doesn't show hand
MichaelDE collected 400 from pot
*** SUMMARY ***
Total pot 400 | Rake 0
Seat 3: gd1990 (button) (small blind) folded before Flop
Seat 5: MichaelDE (big blind) collected (400)
That's an example of a different hand where OP folded on the button and sb also folded to bb.
Just a small oddity on the hand hand but makes you wonder if things in this list have been altered with.
