When I read your introduction to your site you stated that it was created for every kind of post.
This one is strictly about investment for those that don't have time to do the upvoting for themselves.
Definitely not spam.
But your entitled to your opinion (because it's your site) and I won't be using the hashtag in the future.
I just wished you were a bit more polite about it.
Maybe say instead, "This could be considered spam in my opinion. Please refrain from using my tag."

Again, sorry for the misunderstanding.
