Let's take a bit of a closer look at a group of automated accounts that were mentioned briefly in an old thread. 3 accounts crossed our radar at the time; there are at least 5 in the group, with follower counts ranging from 7K - 105K.

The accounts involved are @PeterTownsend7, @PeterTownsendAU, @ptauthor, @pthistory, and @vienna_1683. All are automated via Hootsuite and tweet 24/7. @PeterTownsend7 is higher volume than the other four, which appear to be more or less identical to one another. 
These accounts repeat their tweets frequently - across the 3200 most recent tweets from all 5 accounts (16K tweets total), there are only 962 unique tweets. The most common are repeated 73 times in the timespan, and tweets are shared between accounts, including spelling errors.
What do @PeterTownsend7, @PeterTownsendAU, @ptauthor, @pthistory, and @vienna_1683 tweet about? 99.9% of their tweets containing one or more of the terms shown in this chart, due to the fact that the main focus of the content is to bash on Muslims.
Every single one of the most recent 3200 tweets from these five accounts contains a link. As shown in this chart, almost all of the links are to petertownsend(dot)info. By and large, the site contains anti-Islam posts. There is one more thing. . .
Upon loading petertownsend(dot)info, one is greeted by a banner helpfully offering to sell a book. It seems likely that in addition to promoting anti-Islam rhetoric, these bots have the purpose of directing Twitter users to the site to drive book sales.
