anon, not sure u know about it but there is a maximum limit on how many transactions an account can make. The theoretical allowed limit, based on EIP-2681, for an account nonce is 2**64-2:

It's extremely easy to create a "spoof" token to trick users into thinking a real token has been transferred.

In fact, it only took 16 lines of code to create this fake USDT token below.

I would like to quickly highlight that Polygon has still an enforced minimum 30 gwei priority fee - i.e. if you send a transaction with e.g. the default 1.5 gwei priority fee you are essentially screwed because the tx is underpriced.
