 == Background (back in 2021)
 Downloading logs from mjsoul is more difficult than from tenhou because it requires a login and the log formats are different.
 
-For a long time, the reviewer had been able to retrieve mjsoul logs via https://github.com/Equim-chan/tensoul[tensoul,window=_blank], a tool I wrote to automate the process of login to mjsoul with an account, download of the logs and convertions to tenhou format. I created a dummy account and deployed a tensoul on heroku to provide a more accessible service, then the reviewer could retrieve logs in tenhou format directly by accessing the tensoul instance's API. This was once https://github.com/Equim-chan/mjai-reviewer/blob/b815e32e58414361de5b4af5748cabeb6085e9cb/src/download.rs#L5[hard coded,window=_blank] in akochan-reviewer.

 However, the heroku instance where tensoul is deployed (`\https://tensoul.herokuapp.com`) seems to be banned by mjsoul recently as the login command keeps getting error code 151. Migrating the instance to another region could mitigate the problem, but I have already done it once. Currently both of the two regions heroku provides are banned and I have no choice.
