If you are going to insist on claps, how about a 5-star rating instead? It’s straightforward, everybody understands it, you don’t get people emotionally “clapping” 50 times. (What exactly would, say, 40 claps mean?) Also, “clapping” on my smartphone requires one tap per clap, whereas on my computer I can just hold down the mouse button. This discourages clapping for smartphone users.
