This plugin has a bunch of reviews which were very obviously by its creator. This is scummy. As is combining a legitimate plugin (blocking parked pages) with a useless one ("lets you more easily use our search engine").
Wow, that is a pretty bold accusation with absolutely no evidence to back it up!
First and foremost, none of those reviews were by me, nor did I tell anyone what to say. Secondly, the search engine both a) provides the search suggestions for the block pages and b) has the blocked pages removed from its results. That is, they are naturally complementary.
1) From my other comment (but relevant here)... Those reviews in question (not all, but most) are from Philly people (some known, some unknown to me) because that is the base from which I drew my beta-testers. I solicited them through our local startup mailing lists and clubs. There aren't more reviews because it just went public! The two negative reviews came from an initial release that was broken and wasn't working for anyone :(.
2) Beyond the complementary functions to the user stated above (search suggestions, better search results, search from block page, etc.), there are also many more synergies on the back end. The search engine provides invaluable false positive data to do The Parked Domains Project. Additionally, while the project is good at backend crawling, it has no front end code base at all except for a static Web site, whereas the search engine already has all of that speed/scale infrastructure in place.
3) By your logic, every feature in the Google/Yahoo/whatever toolbar should be its own extension or else it is "scummy?" Or are all search boxes "useless"? Or are you just singling out mine?
