I don't think these spam messages on discord or other social media are effective. In my opinion, theyjust annoy people and don't read anything. Personally, if I receive these kinds of messages, I just instantly block and report the user. Nowadays exist, more efficient promotional mechanisms. For example, if you need to promote your product or account, you can buy followers and likes so that the platform's searching mechanisms will show your content to people more often. Use promoting services like
Famoid and get followers and views under your content instead of spamming people via private messages.
