SOASA shut down in May 2016, after running for three years and screening 9000 people.
So why shut it down?
Running SOASA in a responsible way requires constant attention to take into account things like new scientific findings and security vulnerabilities that can threaten users privacy. Due to work on new projects and starting graduate school, I no longer have the time and energy to keep doing this, and it would be irresponsible to keep the site running.
A big thank you to everyone who used and gave feedback on this site. You made it more successful than I ever hoped for!
P.S. You can see some interesting analyses of SOASA data (and soon an anonymized data dump for researchers) on Quick! To the rat cave!
