They don't even make the effort to get the title of their threads readable. And when they are readable it can be even worse.
I've seen things you people wouldn't believe. "Bitcoin to the moon" off the shoulder of Orion. I watched "Could bitcoin reach 100.000$ ?" glitter in the dark near the Tannhäuser Gate. All those threads will be lost in entropy, like tears in rain. Time for merit.
These posts may sound funny to experienced investors or people active on internet for long time. Most of the times, these posts are made by new members who just heard about bitcoins from somewhere and have no idea about how to invest money in bitcoins. They make threads like "Can I sell my house for bitcoins ?" which is impractical and laughable. These people are not a big concern for the forum as with time they get matured and stop making such posts. Merit system was introduced to fight against people intentionally posting spam here repeatedly.
