For the past few days, I have had mass attempts to subscribe to one of the mailing lists (apg-grantees) for which I am an admin (around 100 last week, 261 this week) from apparently a bot trying to register aol.com or yahoo.com addresses. I have added regex to the subscription filters and made the list not public on the servers to try and fend off further attempts, but I thought I'd report it here in case this has been happening to others.
As far as I can see, deleting unwanted subscribers can only happen one at the time (I couldn't find, like for emais, a "discard all marked differ" button) so having to click 261 times on "discard" takes quite a bit of time.
Here is an extract of the subscribe list for info.
