Just out of interest have you had any legal threats etc from this kind of probing if they don't have explicit bug bounty programs? Also do you ever get offered bounties in on reporting where there wasn't a program?
In Germany, the case of a company called "Modern Solution" has gained quite a bit of traction. An IT guy found a password, tried it on the company's phpmyadmin and reported that he could access their data. They sued him and the case went up to the highest German court, which acknowledged the lower court's decision to rule with the company. The IT guy got fined. https://www.heise.de/news/Bundesverfassungsgericht-lehnt…
When the changes that toughened the § 202 StGB were made in 2007, there were a lot of public rallies against it in which many programmers participated. These were ignored by the politicians in power. This (together with other worrying political events) even lead to a temporary upcoming of a new party (Piratenpartei) in Germany.
The fact that these rallies were ignored by the politicians in power lead to the situation that from then on by many programmers the German politicians got considered to be about as trustworthy as child molesters who have relapsed several times.
