i agree for this to don't reply to trash posts because the important here bitcoin and when your topic is not about to bitcoin don't post.
Yes dont reply to trash posts because your post might be deleted also. Dont reply the post with a non sense thing included. If you reply to that kind of post you might lose your effort or you might be banned or wasnt able to cope up all the requirements needed in campaign. If you will reply to any post be sure that it gives a good reply to avoid deleted posts.
Feeding the troll makes him win like supporting his goals. Ignore it or even report it directly to moderator for his thread to be removed. We don't need any trash posts here, mods are deleting tons of it and it burdens them as there are many users already which compete with bandwidth.
