Siteground blocking Ahrefs crawl bots?

Have any other Siteground/Ahrefs customers here seen this? Just last week all the sites I host at Siteground started showing 202 errors on Ahrefs reports. Google sees the pages just fine and both SemRush and Screaming Frog do not report any problems. I contacted Ahrefs support. They replied very quickly but did not see any problems from their end, suggesting the I may have some setting on my site blocking access. (I checked and so not.) I also contacted Siteground support who also replied very quickly. After they looked into it they informed me that, "some of the more aggressive bots are either blocked or heavily rate-limited on our servers." Do any of you find that the Ahrefs crawl bots are too aggressive for your hosts? I may need to switch from Ahrefs to SemRush which would be a pain since I recently got a paid subscription to Ahrefs after looking at both.
