Definitely. Doesn't always work, but you see a bot buy right after most huge dumps and many times it will make it look like a buy.
How can they fix something that is not broken? The bot instantly buys the nearest ask after the dumps, which most likely is the price before the dump (because of the very illiquid market) and thus sets the price to that. If there is no other buy or sell after that the same minute, the 1m candle closes at the price the bot bought, which is most likely green instead of red. This is a bit of manipulation (someone that tries to make the chart a lot more bullish than it actually is), but this is not something bitcoinwisdom can do anything about.
