Again, I'm not saying he's doing this. Only that this particular business model is the perfect scam as soon as he gets greedy enough. Maybe he isn't this way, but given the general history of "bitcoin entrepreneurs", I don't know why you'd take the risk.
...and then I get sued and held liable for doing so. A significant difference from the bitcoin scammers of the past is that I am not anonymous. There are more incentives to not scam than just good intentions.
I got the sarcasm of the statement but I was wondering why not put a valid BTC address there just in case someone agreeded with the statement.
Because it gives me an opportunity every time to say this: you are a sad, sad group of people begging for change on the internet corner, and it sickens me to the point where I wouldn't put a public BTC address up if you paid me.
We are begging for change! You asked for change, we gave you coins. (This message is encoded on the back of my 25 BTC piece).
Oh, sorry, wrong change.
Well, I agree with the sentiment that just because one could put up a "donation" address doesn't mean one should. I never donate to donation addresses, except on a few rare occasions where I have donated sizeable amounts and paid out bounties for creating code that I thought was a substantial contribution to the bitcoin community, large enough to well overqualify as "tips". But just by putting up an invalid bitcoin address, I don't think anyone gets your intended humor.
