Strange: My wins ratio is stuck to zero

So something strange has been happening for a week or so. I have been using Steamgift for long enough to know how many wins to expect from the different GAs I participate in, especially when constantly trying on low-entries GAs these days.

I haven't won a single GAs, including from Group, Level 5s, whitelist and under 100 entries GAs, for several days which is SUDDEN and RADICALLY different behaviour from before. At first I though it was probability, then It started to feel odd, and now I'm pretty convinced that something is wrong or has been viciously blocked on my account.

So I'd like to know if such behaviour ever occurred to you. And there's no need to talk that bullshit talk about "luck" or "sometimes, the odds and probability blabla", this is part of my job and as I'm telling you this is not natural behaviour.

EDIT: And I just won a GA a few seconds ago, my god.
