I am experiencing the same problem as the original OP. IP matches up as per your publicly listed IPs. How do I stop this. It is a strain on our resources. It is creating 404s, which is very strange, ie, going to the same non existent page every few seconds. Almost like a Neg Seo Attack. Bizarre.
We are not running twitter ads etc, so am at a loss, to comprehend, twitterbot hammering my small business wordpress site every few seconds
Is there an elegant solution apart from the obvious blunt force measure.
