I concur with Jaytea. Changing the comments and removing a few lines here and there may pass... if you were writing a paper and attempting to avoid plagiarism. However here that is not the case, and is more often than not construed as ripped off; resulting in the comments you have been receiving the past few days. The internet is an expansive place and what you or anyone else put on it, it's bound to stay there. Thus making it near impossible to conceal ripped off pieces of work.
