What are Keywordbasket.com & Keyword-suggest-tool.com. Competitors have Tons of these

[chachakhota]

My client is in the Custom Scale Model industry.  They build Custom Aircraft Models, Custom Ship Models and more. Their competitor's Backlinks reports have a Ton of metrics coming from:

http://www.keywordbasket.com  and

https://www.keyword-suggest-tool.com

There is line after line of these entries in the backlink report.  As much as 50 line entries.  what exactly is happening here?  Are they manually using these tools to generate search entries and caching this data in the form of Backlinks?  Please explain.   is this a Gray Hat Tactic?
