Howdy! Thanks for the spam help; I'll try to explain some of the reputation behavior.
One of the biggest confusions might be from the fact that "meta.ifixit.com" has different reputation than "www.ifixit.com." You have the same login but the reputation is tracked separately.
When we go around with the ban hammer and start deleting posts, all reputation and action associated with those posts also get deleted. So, if you were to get 100 rep points on a spam question, you'd end up losing all of those.
We also don't sum ALL your reputation changes each time we display the page, we save it in a cache until a change happens, then sum things up again. When doing Admin actions (see deleting hundreds of posts), things might get out of sync if you are tied into those bad posts. Once we run our rep totalling code again, things will be accurate but the number might change more than you expected b/c posts you had points on got deleted.
We just did a whole bunch of bad things to those questions so anyone's history who has actions associated with those questions is going to be a little wonky.
We have to be heavy handed on the spammers, sorry if your rep is taking collateral damage. Let us know and we can try to fix it up.
