A strong warning about running validators in two places

[superphiz]

Many users will not be aware that running their validator keys in two places will lead to a slashable event and ejection from the network. Users are likely to create redundant systems for backup and may run their keys on two machines to ensure high availability. The launchpad should include a very strong and visible warning that running the same validator keys in two locations will lead to slashing.

This is a very well-known event in the intermediate & advanced user communities, but it is likely to be unknown to beginner stakers.
