I apologize if thise has been discussed before, but I didn't see anything. There has been a rash of new user acounts answering questions, and an equal (rush) to protect them
- 2.1 sound system noise user22024
- Bus vs. seperate return paths for 3 phase bridge? user22023
- High to low impedance microphone user22020
- Mixing AC and DC power in a circuit user22019
And so on. As of this writing all these users can be seen on the main page next to the questions they posted answers to, but now the questions are protected, and the new accounts are suspended. The answers seemed remotely plausible (i.e. not entirely gibberish) though the questions were out of my area of expertise for sure.
On the pull switches question the new user account posted
Whatever you choose, the contacts must be gold plated to prevent corrosion.
On one hand, this answer could make sense: gold protects from corrosion. On the other hand, in this case the OP specifically said that corrosion is not a factor.
What is going on?
