We're very sorry to hear this! Hive SBI was built to support and encourage small accounts, and to provide incentives for bigger accounts to sponsor small accounts with lasting support.
You can always use #sbi-skip in the body of your post if you think it's something more questionable to receive Hive SBI votes on (even if you hide it with html tags, it would still work to prevent our votes).

If that doesn't provide you the comfort you need to post, then you can have the units transferred to somebody else by sending a brief 0.001 transfer memo with instructions. Those kinds of requests are processed manually, so a quick hey can you please transfer my units and pending balance to @somebodyelseplease would do the trick
