July looks like the worst month so far for spam. So far – with about a week to go:
Spam per month (all years together - in development: display only for current year) Total in January: Ham: 924 Spam: 1666 Total in February: Ham: 1454 Spam: 1836 Total in March: Ham: 1843 Spam: 2474 Total in April: Ham: 1812 Spam: 2965 Total in May: Ham: 4549 Spam: 3269 Total in June: Ham: 2010 Spam: 5628 Total in July: Ham: 1559 Spam: 8595
That shows almost a 100% jump in spam in July. Admittedly – I did turn on bayesian filtering in May (lots of bad filtering as you can see) – but the number of spam is just climbing every month.
