As the comments suggest, just ignore it. You will always have disgruntled students even if you do a great job. Some will blame you for their own shortcomings.
But the best "defense" against such negative comments is the positive comments from those who think you served them well. If those appear also, then a reader can easily judge it for what it is.
Let's assume that your primary concern for caring about your rating is that you want students to see you in a positive light for some reason that you hold dear. Further assume that this is personal for you, and you recognize that RateMyProf reviews do not hold much weight for your chances of tenure.
There are two very common scenarios that happen when the ...
You didn't ask a specific question, but I can give some suggestions that I hope help put the matter in perspective.
You are frustrated. Frustration is an emotion that's both legitimate and understandable in the situation you describe. Allow yourself to feel that very real emotion—but, while respecting its reality, recognizing that you can make choices ...
Here's a perspective you may not have considered: maybe your disgruntled student did you a favor.
I used to ask students every semester to give me scathing reviews on RateMyProfessor saying nobody should take me except math-loving workaholics. That way slackers shopping around for an easy TA would be less likely to pick me. Also, anyone that saw the reviews ...

Stop worrying about RateMyProfessor and the like.
Also, "welcome to the Internet. We have cookies".
The same thing often happens with anonymous student feedback, where students try to "get their own back" or even deliberately harm the lecturer. The solution is, again,...
Besides asking them about more clear instructions, I would suggest having two separate sections in your CV:
from that, it would be clear which positions are the teaching ones, and which are research/other.
For this type of applications, it might not hurt to expand the Teaching Experience section with slightly more ...
From the wording, it sounds like the usual work experience section in the CV should be fine, but you should really contact them and ask.
Always include a cover letter.
Never hesitate to contact people who advertise jobs for more information. It can't hurt. If anything, it helps them remember who you are.
Create your own review.
Briefly explain your teaching philosophy. Perhaps make an addendum: very briefly mention the disgruntled student's reviews. (I don't think it would look good to mention the exact rating though.) This is optional and just shows the data (rating) is falsely skewed.
If the RateMyProfessor staff haven't taken down that student's 10+ ...
