I once saw a post about weedcash which said to always use that tag, the next post I made I obligingly used the tag and I got some comment from weed cash to not use the tag on anything but weed related articles, so I just figured the author of the post I had read was wrong and I removed the tag and commented I was sorry. I got a thank you from weedcash for removing the tag. So, yes sometimes you do things not out of malice but ignorance which in reality was my case, and also not thinking things through, but you know, shit happens.
RE: Are you using the tags correctly?
