I frequently get airdropped scam tokens into my wallet. I soft delete them to stop Koinly from showing them on the dashboard; however, they still show up on my tax plan and inflate the number of transactions I have in a year. There are enough of these transactions to push me into a higher tier by the end of the year for the tax plan. I could permanently delete them but they will be automatically imported again when I sync the wallet again.
I think the best solution would be the ability to report certain tokens as scams and have Koinly ignore any incoming transactions with these tokens. Alternatively, the simpler solution is that any soft-deleted transactions should not be included in the number of transactions for the year.
