questions

Hi, is there any way to check all the list(5,796) of "open beta" trophy ?

Sorry, you had to be a participant in the open beta to receive that trophie.

I don't think you can view the complete list, I'm pretty sure it only shows the 20 latest recently collected, and, if it is able to be collected multiple times, who has the most of that trophy.

Oh, I misread your question. You want to know everyone that has open beta trophie? Basically anyone with an ID that is 5800 and lower has the 'open beta' trophie.

For some odd reason that reminded me of the fight\1 URL that generated all of the bots at that time. Tried it just then, and it seems to be patched as I got the generic 'cut the poo' message.

There is not, no. As Draoi mentioned though, any bot with ID 5800 or lower has it.
