Auto termination feature/script
I suggest if there is auto termination of account feature from plesk setting. To elaborate it, accounts more than certain time period will be auto terminated from the server.
> For windows + plesk platform
> For linux + plesk platform
This will ease houskeeping process as well save server resources.
** we have cpanel servers which we can set a cronjob/script to terminate suspended accounts after 3 months suspension.
