Welcome to GPLDL - we are still beta - please report any bugs via the contact form.
@BA: GPLDL is a free service funded by donations. Therefore there are no “payments” or “refunds”. They also provide MANY premium plugins and themes that are not simply copied from GitHub.
I have never encountered any modified code in any of the plugins I have used before. GPLDL is the real deal. No shadiness, all GPL. 🙂️
