I'm commenting(which might be considered spamming) on blog pages(including foreign blogs) manually and creating forum profiles. Im getting 10-30 links a day I have a long term plan with my websites. Do I get penalized by Google for doing this even if domains are 8 year old. Should I use linkwhell for this? Do even linkwhelled sites get sandboxed by Google in the long term. I want to know whats the risk? Thanks.
