I'm slightly mystified by your post Tethersend.
I admit I don't know the ins and outs of this t-shirt design things. But you say these t-shirts aren't designed by pornsick men, but by anyone who would use the search terms.
So who would use those search terms and put them on a babygrow then? 
When I posted to ask people to complain, I kind of thought it's obvious in the FWR section, that complaining isn't done for complaining's sake - it's done with a longer term goal. I know there's a school of thought that says feminists just enjoy complaining for complaining's sake
but it's usually for a long term goal and in this case, it's resisting the normalisation of porn culture. Sorry, I just thought that's obvious, I'm not being disingenuous.
From what I remember of the last incident with Amazon, they said that they would look again at the software so that a combination like this can't be used. That's what the goal is - to make sure companies keep updating software to ensure this stuff can't happen because it's not technically possible. It pisses me off when people come on and start making snidey comments about feminists being pervs whenever this sort of thing arises - if they don't want to complain themselves, that's fine, but FGS, this need to undermine anyone who does, is so trying.
As to having a debate about the slogans -well, not sure what's to say about them actually. Think it might be a bit of a short debate...
