About Senuke

Is there a problem if you use senuke but very gently ?
Like building 10 links a day for forum profiles and maybe 10 social bookmarks?
Can google spot that or is it just such a low volume ?

10 links a day isn't a lot at all. As long as you create relevant backlinks you should be fine. You run into problems when you create 1,000's of backlinks per day and they are not-relevant. As long as you create content that is relevant to what you are backlinking to, you should be fine.
