MBS-14087: Remove subscriptions from accounts after they've been marked as spam

[owlpharoah]

Problem

Accounts tagged spam tend to subscribe even after leading to trivial subscription counts across the site

Solution

The solution is to remove all types of subscriptions off of accounts when they are marked spam from the admin menu.

Testing

tested it locally by marking an account as spammer and then checking change in subscription.

Thanks for the patch. This is something that makes sense, but we need to be careful about immediately purging data like this, because people can be marked as spammers accidentally or based on a misunderstanding. In a related ticket (I can't find it right now, because Jira isn't working) we discussed adding a cron job that runs monthly and moves spammer data to another schema. That's the direction I think we should go in, so I wouldn't accept this patch in its current form.

hi! thanks for letting me know. I'm assuming the ticket youre talking about is MBS-14096. Regarding that ticket, is it necessary we have a whole another table for spammers or instead just run the cron job to check when last updated on the same table and then make a deletion.
