It is hard to differentiate a bot pump from a normal pump, really. I have seen many pumps before and most I thought were made by people, only to realize that the majority of the pump was executed by a bot (Willy, for bitcoin).
It's technically easy to create a roadmap before pumping a coin. Actually you can copy from any other coin and just rephrase it a little bit just to make it look legit and original and then afterwards proceed to pumping phase. Deliver a couple of things indicated in the roadmap, pump the coin again and then, $$$.
Not all coins with good presentation and road maps are really there for the long-term. Others will just shit on you and burn your money.
