I'm sending my blog links to various search engines/directory submission and also creating manually backlinks on tumblr, reddit etc of my wordpress blog. Now, I'd ask if posting too many backlinks would be marked as spam by Google. I mean, if I copy many links and articles that redirect to my blog and start spamming on blogs, and web can be harm my blog and get a ban from Google? My articles on my blog are interesting and getting around 200-300 visits per day, so If I don't spam much around I think I can be safe.
