And if you make a fake block that changes the address, then the fake block is not a good one.
This avoid the same problem with people stealing from pools, and also evil people listening to new mined blocks that pretend that they found it and send a fake one.
Realistically, the bot owner could notice you're running MoneroAnubis and then would specifically check for MoneroAnubis, for example with a file hash, or a comment saying /* MoneroAnubis 1.0 copyright blah blah GPL license blah */. The bot wouldn't be expected to somehow determine this by itself automatically.
Also, the ideal Monero miner is a power-efficient CPU (so probably in-order). There are no Monero ASICs by design.
I doubt you could do this efficiently enough such that an mining-business optimised mining rig can be kept busy enough with web-scraped honey pots to be worth the think time of setting it up vs. just scrape and skip pow protected sites + dedicated crypto mining operation as 2 seperate things.
Then it's the bots who are making money from work they need to do for the captchas.
