In many ways, this is an inherently unanswerable question, and it's just about as unanswerable for US citizens as well. At it's root, the problem is that you've left information scattered around the internet, much of this information is possibly stored indefinitely in various US intelligence agency databases and that this information can be used to make inferences (correct or not) and judgments (fair or not) about you and your actions. It is also possible that information may be framed in a manner so as to give a misleading impression of you and your actions.

Being outside the US is both an advantage and disadvantage with regard to these programs. The advantage is that you are in a bigger pool that is likely less interconnected with those who have access to this data, and so are less likely to be targeted by abuse of the information that has been gathered around you. The disadvantage is that it appears that if you did end up being targeted, it seems less likely that such targeting would rouse suspicion since the privacy rights of non-US citizens do not seem to be getting any consideration from US officials at all.

The difficulty with these questions is that people try to think of scenarios by which information can be used against them. This isn't really a productive exercise since failure to come up with a reasonable scenario in no way proves that one doesn't exist.

Perhaps a better question is "Could anyone with access to this data ever want to hurt me, my relations or our respective reputations?". Implicit in the question is the assumption that anyone with said access is capable of hurting you or your reputation by releasing it strategically. Some may argue with this assumption, but I would challenge that few, if any of us really have a handle on just how much data we leave laying around on web servers outside of our control, and so are ill equipped to make judgements about how it might or might not be used against us. This question too is very difficult to answer with a reasonable level of certainty, but it at least leads us to some more productive questions that get at the breadth of the problem:

"Do I, or any of my relations ever openly or privately (in channels controlled by US intelligence programs) make strong political statements?"

"Do I, or any of my relations play a visible role in any company or organization that someone with access to this data might find morally or politically disagreeable or inconvenient?"

"Have I, or any of my relations injured, spurned, rejected, humiliated, or otherwise hurt, physically or emotionally, anyone with access to this data?"

"Will there ever be a scenario where I, or any of my relations are put into direct or indirect competition with anyone with access to this data?"

"Could someone with access to this data ever want to randomly target me or my relations for kicks?"

"Could a malicious 3rd party ever gain broad access to this data and use it in a way that hurts me or my relations?"

These questions get at just how broadly the effects of abuses of this data could reach. Will you be targeted for abuse? It's extremely unlikely, there are 6 Billion people in the world, and there are certainly bounds on the amount of harassment that can be done secretly. But nobody is really immune from being effected by abuses of this kind of data. There are innumerable strong personal incentives for abusing data such as this, and the more of it that's out there, and the more connected, organized and searchable it is, the more likely it is that abuses will happen.
