It doesn't make them a troll (IMO, you need to have a pattern of behavior to be a real troll) but it makes them potentially guilty of perjury, which is kind of a big deal.
DMCAs shouldn't be filed lightly (unless you have the legal resources of the RIAA/MIAA/etc to dissuade your targets from retaliation).
Not a lawyer, and haven't talked to a lawyer? Don't file a DMCA no matter how butthurt you are about being 'copied'. Just because it is relatively easy to do doesn't mean you should do so in the spur of the moment. It is a Real Legal Thing with Real Ramifications, and this is good because it limits the amount to which bad actors can abuse it, but it also means you should be really sure you're the victim of copyright violations prior to using it yourself.
