Working in an industry that is considered shady can harm you in the long run. I have worked at one point in a gambling (So called "Gaming") company and 80% of the people there only move to other gambling companies (or even shadier places) because there is a bias against them in "regular" companies. I would also add that the longer they stay in the space the harder it is to leave it without a significant pay cut / position downgrade. This is not only limited to developers but marketing, hr and product as well. Fields that I would especially be wary of entering or spending time in are: * Gambling: Including real gambling ,virtual points gambling and gatcha games * Gambling disguised as financial services: Gamifying Forex/Binary options and other "investments" * Predatory financial services: Like payday loans and high yield loans * Areas that you need to explain why your specific company is not a scam: Crypto/NTF etc * Actual scams: Like toolbars (you would be surprised but its still a thing) and anything that is just thinly veiled phishing The same advice goes to entrepreneurs and not just employees. I would advise to stay away from VCs that have any significant amount of investment in these fields (>10% of portfolio).
