This basically opens a whole new can of worms. If you want to ruin a projects reputation, say they're your competition, just hire a bumping service on their behalf and soon they'll be tagged as cheaters or at least shady.
Something to consider anyways
I guess there is a chance for something like that to happen ( highly unlikely imho), but but even then OP can report those spammy posts and mods will delete them, or in case of Minereum he can delete those posts by himself, as their thread is self-moderated, and it seems that he is not doing that.
Most of these altcoins are so bad that they don't even need some external enemy, their own incompetence and delusion are more than enough.
True, but some of them after being idle for a while all of a sudden have bumps and the OP / creators are nowhere to be seen.
Makes you wonder if some large bag holder someplace woke up, looked at a wallet filled with crap coins and thought, it's worth $100. If I dump another $100 into a bumping service I can get the price from
BTC0.00000001 to 0.00000025 and make some money back.
Also, kind of wonder how many people are like me. Been in this game for a while and have their old favorite crap / junk coin that is worthless now, will be worthless later, but still enjoys playing with it.
