On Wikipedia, that is an extraordinarily rare occurrence; maybe one big case of that comes to light every six months to a year. That may amount to one out of every, oh, thousands of blocks, and even then, the user who is crying abuse often has a history of "gaming the system," or subtly circumventing policies to create a long streak of disruption. To say the least, administrators are rarely removed of their rights for the reason of misusing them.

Since Wikia has many small wikis, however, with one or two admins and even fewer active users, they might be more tough in handing out blocks for various offenses than a Wikipedia administrator would be, but this is rarely constitutes "abuse," which, as Tupka217 inferred, is a very subjective term. If one feels as though an admin has treated them unfairly, they can always contact Wikia staff, but their edit history and attitude usually speaks for itself.
