Your post reminds me of this one:

Your first picture looks like grasshoppers though the small holes look like something else.
Several bugs like pepper plants:
Caterpillars, whiteflies, Red Spider Mites, Thrips, Pepper Weevils, Snails, or Slugs.
In the other thread, a worm was finally found so caterpillars very well may be what is eating the leaves.
Keep looking and maybe you will find out what is eating the leaves.
If it turns out to be caterpillars just pick them off and drop them in a pail of water to drown them.
