As a writer for long years, I haven’t seen such support – ever.
I’m talking about spam. SPAM actually makes you write more.
SPAM is supportive, maybe sometimes irrelevant.
You want to keep spam, just to show your users that there is some kind of activity in your blog when it’s new.
As a writer for long period, I rarely did get some comments on my writing therefore tuning into comments can be a great deal if you want to be encouraged as a writer.
There’s nothing worse than no feedback on your work.
So the SPAM comment makes it a little better even if it’s not true.
