I don't think that 'profit' means the same to you as it does to me. At adsense income levels reocities will never be profitable, and I have a couple of thousand thank you notes collected by now that prove that on the whole people are pretty happy that I did what I did.
People that request removal of their pages have it backed up now (I do that for whoever asks to create a zip file of all their content), and those that don't want their old stuff online any more because it is either inaccurate or because they can't update it (reocities is 'read only').
In some cases they want it removed because they put private info online back when everybody did that or because they are now professional designers and don't want their geocities stuff to haunt them.
And, of course, whoever asks has their content removed, once every month or so I filter my inbox on 'reocities' and 'geocities' to process the removal requests.
It's still a manual process, that's how little it gets requested, but I probably should automate it somehow.
If in the long run reocities contains no pages and all the stuff has been moved to the proper owners again then I'll be more than happy, that would be the best outcome.
Having some adsense ads in there was a way to offset some (but not all by a long shot) of the hosting costs.
