I have no problems at all- and you can disable ads in your control panel. If you get autoplay ads, please get a screen shot, as we don't allow those.
I'm not an IT person, but if I can use it at work (don't tell!) on IE and at home with chrome, without so much as any sort of install/malware warnings/talking ads/etc it seems that the problem isn't with our site. I'd suggest running malware software for sure. And like I said, please grab a screen shot of anything that comes your way, so that Austin and TxBrew can take a look to ensure our site is safe.
Spammers are a bit tougher- we don't want to add a captcha, and we don't want to over-filter but they are still trying hard. There is a "report this post" button on each post, and please use it as we respond to reports very quickly. Thank you all for helping us keep the site as 'clean' as possible.
