I've played since the game's launch and I've definitely been in more than 5 guilds-guilds rarely seem to last longer than a year, many don't make it longer than six months, and sometimes you cannot help it when guild leadership implodes or people get burnt out and leave, etc. I've left lots of guilds because the leadership was poor. Only in two cases did I leave due to personal issues, and in both of those cases, I was an officer and had a major disagreement with the way GMs were handling things.

Every other time, it was because leadership quit, or seemed corrupted after awhile, or because raiders stopped raiding and I wanted to raid, etc. It had little to do with me on any kind of personal level at all, just a "I want to raid, and the guild isn't really raiding anymore, and all the people I like quit out of boredom or to play another MMO that just came out."

My long-winded point is, there are plenty of people who have legitimate reasons to cycle guilds, and it should not automatically be a factor in being wary of a player. Things happen, people move on, guilds dissolve or explode, and frequently, this has very little to do with the player in question.
