As the sister comment says, it's because your comment doesn't make sense. What does "test????/photo????" mean?

It's an obfuscated reference to a popular open source data recovery toolset. I think the parent was trying to avoid potentially "outing" GP against their wishes, by making a vague reference that some might get.

Well, it's a guessing game to know what company the parent parent is referring to and there are two well known recovery software but I didn't want to give out the name so others could keep on guessing. So I just wildcard masked the thing.

I reckon people find it uninformative. If not, then I'd guess the exact opposite. You should know which.

I think because the comment is confusing. Are the question marks a text encoding error?
