No, but we acquired this domain and 301'd it to our main domain and acquired all of it's link spam in the process. It's made our link profile look like this:
- Foreign Character Spam: 69%
- Natural Links: 7%
- Tag/archive links: 6%
- Other: 6%
- Feeds: 5%
- Affiliate: 4%
- Guest Post: 3%
There's been very minimal cases of link farms, but the link profile is what is worrying me.
