Just FYI, we've been around since there were only a handful of prediction markets and other Bitcoin books. We were one of the first to process 1000 BTC worth of total volume as well. We do not use Facebook or Twitter anymore due to privacy reasons as we are very firm believers of the original intent of Bitcoin and its anonymity.
If you make one post per year and it seems like elsewhere you're also inactive, it may appear to many that the site has been abandoned. That perception could also lead to a lower bet volume. Good that you have at least updated your twitter and fb.
We replied to the email that the user sent us a week ago - sorry for the delay, the user used a strange address that didn't pass our back-end syntax on the payout side even though it passed the front end. We'll get it sorted out and fixed for future.
Any ETA on that? bech32 addresses shouldn't be considered 'strange' anymore.
Our team will be looking into bech32 after this busy election season. Currently, we have seen less than 0.1% of bech32 addresses accidentally inputted and surprisingly all of them except this one user lost their bet so we haven't been notified until now. In addition, one user tried to use it as a withdrawal address but the system correctly rejected it.
No point spending development resources on something largely unused by the community at this time.
