Remove spam confirmation requests

Too many pending subscription requests can slow down[1] list index. Updating postorius is how to fix this. But in case there's no other way, and removing those requests through frontend [2] is impossible, this can be done:

$ sudo mailman shell -l listname.lists.fsci.org.in
Welcome to the GNU Mailman shell
The variable 'm' is the listname@lists.fsci.org.in mailing list
>>> from zope.component import getUtility
>>> from mailman.interfaces.pending import IPendings
>>> pendings = getUtility(IPendings)
>>> plist = []
>>> for p in pendings.find(m):
...   plist.append(p)
... 
>>> len(plist)
2047
>>> # Let us save the spammer email and when they signed up for analysis
>>> import csv
>>> with open('spam.csv', 'w', newline=) as csvfile:
...     spamwriter = csv.writer(csvfile, delimiter=',')
...     for p in plist:
...         spammer = p[1]
...         spamwriter.writerow([spammer.get('email'), spammer.get('when'), spammer.get('display_name')])
...
>>> # Now on to actually removing spam
>>> from mailman.interfaces.workflow import IWorkflowStateManager
>>> workflow = getUtility(IWorkflowStateManager)
>>> for p in plist:
...     token = p[0]
...     pendings.confirm(token)
...     workflow.discard(token)
...
>>> # Now, we have to commit this transaction to database
>>> from mailman.config import config
>>> config.db.commit()
