three points here, first next time please leave better change set comments, for more info see:
https://wiki.openstreetmap.org/wiki/Good_changeset_comments
things like swimming pools and land use are best mapped as areas, please stop adding these as points. third, I doubt that a tennis pitch has a address, that address is part of the building not only for the tennis pitch so please stop adding info to addresses when those addresses are not only pointing to the feature.

Happy mapping,
Udar
