I usually don't belive that those jr. members and newbies posting in the alt section are not bots, simply, they post rubbish, I just can't belive they are humans and do this manually day by day...
It's a mixture of the two. There are some ICOs/alts that use bumping services which use bumping bots. Another, exploit is by offering an incentive to post on their thread, and then finally it's just users that are trying to earn money, and post something good about the project in order to gain some favour or something.
You just can't report all of the spammers and get them banned, because if you get one banned, two or three new shitposter will register immediately... (unfortunately, even if you won't get one banned, the new shitposters would still register...)
Yeah, but this is where we could go for softer restrictions, and try to make up for it via actively reporting. Judging by how long it takes for a report to be handled the moderators aren't completely swamped by reports. If we could increase the amount of users reporting then it could make a difference. It would be nice to have statistics to offer insight into this, and whether or not reporting is actually doing something. I'll continue to report regardless, but it does feel like a losing battle most of the time.
