I've moved into the current place for a few years.
Since Day 1, I have put a sign up at the front door:
"Do not knock. Sales people and charity are not welcomed."
I also have a camera pointing at the front door.
I work at night and need some rest during the day.
Everything was fine until the 2nd half of this year,
perhaps people suddenly realize that making money is not as easy as they think,
or people have spent all the $ from gov payments during covid,
more and more people are knocking on my door,
from new car service mechanics wants me to prepaid $250,
to corrupted World Vision hunting for my donations.
They just don't read the sign.
What else can I do to stop them?
Thanks in advance for all helpful suggestions.
Might work better if you wrote it in different languages:
لا تقم بالطرق، لا يمكنني التحدث بالإنجليزية.
請勿敲門,無法說英語。
សូមកុំប្រើប្រាស់បន្ទាន់ទេ។ ខ្ញុំមិនអាចនិយាយភាសាអង់គ្លេសបានទេ។
ਦਰਵਾਜ਼ਾ ਨਾ ਖੋਵੋ, ਮੈਂ ਅੰਗਰੇਜ਼ੀ ਨਹੀਂ ਬੋਲਦਾ।
Usigonge, siwezi kusema Kiingereza.
