Not when actions and events can have multiple, unknown meanings. A like in the app can cause your bot to transfer 10k sats, in the background, to the note author. Repost + like combo could mean "send 50k sats". Replying with "Love it, your art has inspired me to grow 100x" could be code-word for telling the bot to send 100k sats. Etc etc Its already happening, just in small scales. Apple cannot ban "likes" or cryptic replies that *might* trigger a remote payment.
