+1 here too. Picked it up on my phone, surprised it got round the spam filter.
But more to the point, if the RAF Club's accounts / servers have been hacked, what personal data other than email addresses are now compromised? It would be a reasonable assertion for anyone with malicious intent to assume that there will be a fair number of members who are currently serving as well as retired. Are their home addresses now compromised? Would be worth the RAF Club investigating the extent to which their systems have been compromised in case it was a deliberate attempt rather than a lucky spamming operation.
