My view is that:

1) His original reason for avoiding Saidit was to spend time with ill family members, which I think involved leaving Texas to visit them elsewhere for a few weeks. Something at this time meant that he reconsidered his approaches to Saidit, and let Amelia and d3rr take over at that time.

2) He continues to stay away because of personal reasons and - because we like conspiracies here at Saidit, and because M7 mentioned that he had online enemies - I'll propose a conspiracy theory that he knew that he and perhaps Saidit had been exposed for 'hate speech' (something Amelia considered). Not that this is a major problem for cloudflare.com, particularly with regard to Saidit, but look at what's happening at other so-called "fee speech" right-wing websites. But all of this is backstory for the conspiracy theory. M7's open criticism of the Rothschilds and their very well connected ilk very likely made him a target - even if only a low-level target - because of his ownership of Saidit (a valuable and influential website). There is a long history of Jewish groups threatening influential people who could have an impact on the the wealthy Jewish population and Israel supporters (/u/Jesus has some material on this). A letter from one of these people is very easy to arrange, or from the CIA or the FBI, regarding hate speech or whatever. M7 knew that he could back away from his public role at Saidit, and much of the harrassment from these people would likely drop somewhat. It's also possible that there are legal problems with Saidit, and if so, M7 can't say anything during the legal process. Most importantly, his initial reasons for leaving were related to concerns about the health of family members. This is enough to change anyone's one's approaches in this manner at Saidit.
