Hi @zhengyh
The baseline models will be excluded from markets from next week just because many participants are concerned about their presence.
The mean model is the only one that made it through in week 2 and I am attaching the feedback. Please note that your model is not likely to have been in many markets with the mean model due to our randomisation in relative terms.
Regarding the multiple accounts, thanks for noticing that! Indeed this is not allowed site-wide and the terms of use are being updated to reflect this fact. I will respond here once that is done and link you to it.
I should re-iterate that the baselines will be excluded from this week
