Well it depends. If you use the suspension length days entry as…
I will now enter a number that represents how much I hate this user
Then they will treat it like that. So .. don’t do that? Always suspend everyone for the same amount of non-ridiculous time, say 5 years. Don’t put them in a cannon and launch them 9999 years in the future.
Of course, people will be able to discriminate between users who were suspended for a brief time because you want them back, and those you do not want back, but that’s unavoidable.
