Questions you'd like answering, regardless of how trivial they may seem

I do run adblockers, but these aren't adds, they're suggestions supposedly based on your search history and tracking cookies. It only takes seconds to use the 'Clear recent history' on Brave.

If you’re using a google account it’s most likely google giving you crap ads so you agree to their behavioural content opt in.

The UK mains supply is 240V.

Not officially.

In 1995 the specification for appliances to be sold throughout Europe was set at 230V +10%, -6% (216-253) so that the same appliances will work across Europe without modification, and without anybody having to change their supply voltage. In 2003 it was further widened to 230V +/-10% (207-253).

And the UkK mains supply is officially 230V, but with that wide tolerance meaning it can actually still be around 240V for most of us.

Why is the 'More to Explore' section of my Ebay app suddenly flooded with suggestions for vapes? I'm not a smoker and have never once searched for vapes for sale anywhere.

To stop tracking, I always search for items while logged out on the main PC making a note of the item number and then clear cookies, search & device history before either logging in on the PC or using the app to search for the particular item I'm interested in. Once done I clear the viewing & search history again so the only things it should show me are items similar to anything on my watchlist (a couple of bikes ATM). So why vapes?

Because you clear all your history, so it has no idea and just sends you some of the most popular suggestions.
