This is a sample message you could use to send to a suspected spammer on your group:
I am sorry to be writing, but need to tell you that your membership of our Freegle group has been suspended. This is the second time you have sent spam messages to the group.
Now, to be fair, we don't think it's deliberate, and you've been
suspended not as a punishment, but to protect the group.
It's almost certain that your computer has been infected with some
sort of malware. It's probably sending these messages out to all your
address book in chunks and at intervals. You may have received other complaints from friends?
What you need to do now is scan your machine, not just for viruses,
but also for trojans, worms, and the various other nasties that can
cause mayhem. There are some very good programs out there which can
do this, some even free for home use. There are also a number of
websites which offer a free scan of your machine, but if you search
for these, be careful, as a few are a cover for software which will
actually infect your machine! Best to go for those referred from a
computing magazine website or similar trustworthy source.
Once your machine has been thoroughly disinfected, before you do
anything else, CHANGE *ALL* YOUR PASSWORDS, especially anything
related to finance!
When you've changed your Yahoo log-in password, please let us know and
we'll reinstate your membership.
A word of caution. If you ignore this message, and we continue to
receive spam emails, eventually we will unsubscribe you and report
your account for sending spam out. We won't, and don't, do this lightly, but
it has happened in the past when the level of spam has become
intolerable, as it will eventually do if you do nothing.
If you need any help, please do ask. We hope your computer is sorted out soon.
