Spam is repetitive, insulting, or irrelevant text that disrupts other users. Making several threads at once can be seen as spam, depending on the context. Please know that if you choose to do this outside of a “controlled thread”, your posts will be be marked and deleted.
“Controlled threads” are threads that are made specifically for spam-related messages. As long as you are not disrupting other users, it is OKAY to create and make use of these types of threads.
