As of today, supawin rep didn't responded yet and the site is currently down for this moment.
[EDIT] I just saw one of the admin's message on its telegram group, and seems the team is currently working about the site, though never responded related to the signature campaign.
The campaign thread has even been locked. Not even a mere response from the Supawin rep, and yet he/she has been online.
Spreadsheet's view access has also been revoked without and update.
Very unprofessional as certain [participants who have already won signatures probably do not know even about the developments
The spreadsheet was also locked and asks for permission, I guess it should be removed already and OP conducted a free advertising.
