True, but it's still better than overlooking the unbans entirely.
By the way, we should mark the day 09 May 2019 as important day to say one year anniversary of plagiarsim-finding bot next year. Furthermore, from 09 May 2020, there are so many permanent banned users whom got signature bans as alternative punishments will be fully back. There will be important day around 09 May 2020.
Yesterday, 400 users got banned. The day before, 300 users got banned.
