Yes, I partly admit my guilt. I admit only partly, because the percentage of plagiarism in these my 3 posts is minimal, and even in Universities during the writing of scientific works now allowed the presence of plagiarism at the level of 30-45%. Yes, I was stupid that I did not care to put a link to the source, but this is my isolated cases and I am not a malicious copy-paster.
I ask you to remove my ban or limit it to any period.
Now this was a major waste of time reading this thread.... Not to mention the other guys that investigated this... Now, would this deserve a ban on the new account?

I'm not sure which universities you are referring to (and it's a shame if this is happening in some countries) but where I'm from, for the thesis I've created, the only accepted way to copy stuff from other documents was to
specify the source. Specifying the source for the
short paragraphs you copy is not considered plagiarism.
