I don't know how to avoid scraping profiles below that threshold, but you could use a regex to only grab the numbers which meet your threshold. If it does not, then WS will fill in "null" in that field.
The regex is: (\d{2,}k)|(\d{2,}.\dk)
which will grab text like 10k, 11.2k, 32k etc. It will ignore text like 8900, 9k, 8.9k etc. The sitemap below illustrates. I also grabbed the likes and ran it thru the same regex, so you can see more "null" fields. Later you can use Excel or Google Sheets to filter/sort out the "null" ones.
