pff, I think I am save. Posting links on these platforms scare me now honestly

I run an Adobe user group for over 25 years and I have been banned twice on Reddit for merely posting notices of livestreams and YouTube links of finished videos. Never failed to get less than 10-15 upvotes yet I still got banned.

That is Reddit's problem, not yours. However it does help to spend some time in the forum, answer a few questions and get known before posting about a product. It is also not a problem when answering a question to have a link to your product in the signature.
