Plesk generates the private key for the DKIM and stores it securely along with the private keys for SSL. When you send an email from Plesk with DKIM enabled it Plesk uses the private key to generate a DKIM signature that remote mail servers can use the public key provided via DNS to verify that the email is legitimate.
You're welcome to work on gnu social here, just keep an eye on your load chart https://heliohost.org/dashboard/load/ If you need more than 10k CPU you can upgrade to Morty at https://heliohost.org/dashboard/move/
The Softaculous software you installed are pmwiki and gnu social. Neither have anything to do with AI. We think the load may have come from Softaculous trying to do a daily backup of the the gnu social program you installed. If you were editing the gnu social source code maybe that's why Softaculous acted so strangely. Unsuspended.
Why did you unsubscribe from our emails? Was it a mistake? Why did you expect to get an email after telling us you didn't want to receive any emails anymore?
Can you explain why you need to send emails from Morty (which has been deleted) and Johnny (which your account is no longer on)?
I think this SPF makes more sense:
"v=spf1 ip4:65.19.154.93 ip6:2001:470:1:1ee::1011 include:_spf.google.com include:smtp.spf.ziggo.nl ~all"
