What do you mean by influencers? If you mean by that is about manipulators, no you should never, because there are too many and situation may always does not support them, so you can follow.
Unfortunately, often the market manipulators come across to the general public as consultants who just happen to be very good at trading. It's not like they put "Market Manipulator" or "Pump and Dumper" on their Twitter profiles. But some of them have been caught red handed using their subscriber base as fodder for their manipulation schemes. In some cases, their subscribers have been paid subscribers, which makes that abuse all the more blatant.
If you follow an influencer and they start promoting a coin, ask why before you buy.
