There are some groups that will public whatever they want just to keep the thread up on the first page, and also saying positives things about the project, mostly because they already invested on in an ICO or Pre-sale, so they try to secure their investment, and because this project has already a successful PRE-ICO, they will just start with their spamming here and some other forums and chats, some are good at hiding their intentions, others not much, but a lot of projects have them, is inevitable, you just look into the project and judge it yourself, and you'll see if the project is good or not, forget about the spammers or bots, they don't have a valid opinion.
