ProxyLista.com ( ex. azproxYs.com ) is a spanish proxy list website. Unfortunately most proxy webmasters are not able to submit a proxy because they don't understand or don't want to search for the submission form.
To submit a proxy click "Sugerir Proxy" in the menu.
Link directly to the submission form: http://proxylista.com/sugerir-proxy.php
Currently the listed proxies are receiving good traffic because the competition is very low in the list. Since 1 month no proxy was submitted.
