I’ve just moved to Dreamhost to avoid the problems I described above. I’m still getting tons of spam, but at least Dreamhost aren’t threatening to suspend the account.
My previous host was UK based supanames on their value pro account. It wasn’t really set-up to cope with a wordpress install as I had to manually ask them to allow outgoing pings to things like akismet.
So things are better, but I still get a deluge of spam. Any way to stop the bots before they reach my site?
