75% I agree. However, re: plagiarism one has to be careful and refer to the whole post. I got a cheetah comment (not flagged thankfully) for a post I added which included information from an article my cousin and I wrote about our Great Grandfather. It wasn't cheating nor plagiarism, merely adding from our own work.
I would hate it if someone literally stole my work and I agree that must not be allowed to go unnoticed/unpunished, but people have to be a little savvy and restrictive in case it is a legitimate copy of ones own work elsewhere.
As for spamming, I haven't flagged one yet - and didn't realise I could just for spam content. I simply ignored it. I will move forward with the extra info.
Thank you for your informative posts. I do like them. I have followed you for a while now because of that.
I'm not in it for the money though, just for fun and recognition. I write short stories, poems, and I paint so I never expect a follow back from people who don't participate in these areas.
