To scrape Reddit without needing an expensive and complicated crawler, you can use AutoSERP.dev, a service that allows you to extract data from any website using a search query.
Register for a free account on AutoSERP.dev, create an endpoint, and obtain an endpoint ID and an API key.
Use a specific search query to limit the results to Reddit and include the keyword you're looking for, and you can also add filters like a date filter.
Specify what data you want to extract, such as a short summary of the initial poster's problem, and use the requests library in Python to retrieve the data from AutoSERP.dev.
