That’s the type of thing that will get that account deleted for vote fraud and sock puppetry. At that point, all of the votes it cast will be invalidated and all of the people you’ve tried to help by casting upvotes on their questions in the effort to be nice will lose those votes and that rep.

That will leave a sour taste for many developers and will probably turn many of them away.
