Normally SEO firms are accused of adding garbage to OSM. The worst offender, what I refer to as "SEO Updated" is a prolific firm adding poorly tagged companies. Fro the week of Jan 28th through February 3rd, SEO Updated added 27 businesses. The only good news it that they only seem to operate on weekdays. I believe DWG is fully aware of their operation.
Another offender came to my attention. This SEO firm, Milestone Inc. in Santa Clara, CA. is not only adding poorly tagged companies but they are deleting existing building outlines with some of the same information they are adding, but only as a node. Like SEO Updated, each business has their own user name in almost the exact same format. Another similarity, they don't respond to changeset comments or messages.
Their Operations VP has not responded to my messages nor has one of their customers, Best Western Hotels. So today I'm going on Twitter to shame them into responding. I could use your help. Please retweet or post your own to @milestonemktg. Please use the hashtag #DestructiveSEOedits.
